摘要： An optically bistable device, such as a symmetric self electro-optic effect device (S-SEED), is forced into a metastable state prior to the incidence of an optical input signal thereto, thereby increasing the sensitivity of the optically bistable device to the optical input signal, reducing both the switching time and the optical input signal energy required to switch the device. The metastable state is entered into by one of three techniques: (1) turning off the bias voltage V.sub.0 of the device with optical bias beams on then turning on the bias voltage V.sub.0 with the optical bias beams off; (2) applying a predetermined voltage to a node in the device, the predetermined voltage being substantially the metastable state voltage or V.sub.0 /2; or (3) subjecting the device to equal intensity optical bias beams having a wavelength longer than the exciton wavelength. In the second case, optical bias beams and optical input signal beams may be applied simultaneously with the application of the predetermined voltage. In the last case, optical bias beams (at the exciton wavelength) and the optical input signal beams can be applied simultaneously after removal of the long-wavelength optical bias beams, thus saving switching time. In addition, the optically bistable device may be selectively placed in the metastable state and the optical input signal have sufficient energy to switch the device only when it is in the metastable state. This allows for multiple optically bistable devices to be selectively responsive to a common optical input signal, such as in a demultiplexer.

摘要： Lower switching energies, enhanced electroabsorption and reduced tolerances on the operating wavelength of incident light are achieved while contrast between low and high absorption states is maintained in accordance with the principles of the invention by a self electrooptic device including an intrinsic quantum well region having an asymmetric electronic characteristic across a narrow bandgap subregion between the two wide bandgap layers defining the quantum well region. As a result, the quantum well region polarizes electrons and holes within the subregion in an opposite direction relative to a direction for an electric field applied to the device. The asymmetric electronic characteristic is realized as a compositionally graded, narrow bandgap layer or as a pair of coupled narrow bandgap layers of differing thicknesses separated by a thin wide bandgap layer.

摘要： Optical apparatus is disclosed wherein narrow line width light from a source is directed through the substrate of a semiconductor structure and reflected from the gate electrode of a field effect transistor element fabricated on the surface of the semiconductor structure. A quantum well layer serves as the current channel for the field effect transistor, and charge carries from a doped semiconductor layer provide high mobility carriers in the quantum well layer. Changes in the potential between the gate and source electrodes of the field effect transistor causes the normal pinchoff of carriers in the quantum well layer thereby causing changes in the absorption characteristic presented by the quantum well layer. By directing light from the source at the gate electrode through the substrate of the semiconductor structure, a photodetector can be positioned so as to detect a change in light which has passed twice through the quantum well layer, thereby detecting a change in the electrical state of the field effect transistor.

摘要： An optically bistable device 100 is disclosed having a self electro-optic effect device (SEED) 104 and a variable optical attenuator 103 for maintaining the state of the SEED over a wide power range of two input light beams. The SEED is responsive to the relative power levels of the two input light beams for assuming one of two states. The state of the SEED is determined by the transmission level of one of the beams passing through quantum well region 102 of the device. The variable optical attenuator concomitantly varies the power level of the two input beams to maintain the present state of the SEED over a wide range of input light beam powers. When operated in a bistable operating region of the device, a control light beam with a low power level changes the device from one state to another. Two threshold values of a ratio of power between the two input beams establish where the device switches from one state to the other.

摘要： Improved integration of optoelectronic devices is provided by a spacer layer laterally sandwiched between distinct regions that are monolithically fabricated onto the same substrate (e.g., by selective epitaxy). An optical waveguide in one of the regions can optically couple to an optoelectronic device in another of the regions through the spacer layer, thereby providing a monolithically integrated form of butt-coupling. Preferably, the spacer layer thickness is less than about 50 nm, and is more preferably less than about 20 nm, to reduce optical loss. The spacer layer is preferably electrically insulating, to prevent shorting of devices grown by selective epitaxy.

摘要： An electro-optic semiconductor device (e.g., an optical modulator) having side access and beam propagation within the device is provided. Side access for the optical input and/or output facilitates disposition of electronic circuitry and/or heat sinking structures on the top and bottom surfaces of the modulator. Internal beam propagation instead of internal waveguiding advantageously simplifies optical coupling and alignment to the modulator. Interaction length within the device is preferably enhanced by passing through the device active region at a relatively shallow angle. The internally propagating beam is reflected from a reflective face parallel to the device active region. The side faces can be perpendicular or tilted with respect to the reflective face. Tilted side faces are preferably tilted to provide external beam paths parallel to the reflective face. Internal reflection from an angled side face can be employed to provide configurations having one side port and one top or bottom port.

摘要： A novel method and device for separating light of differing wavelengths (wavelength demultiplexing) uses a very simple and compact multilayer dielectric structure having high angular dispersion at certain wavelengths and angles of incidence. The structure is composed of alternating layers of dielectric materials of different refractive indices, and is designed to operate just outside the main reflection region rather than within the main reflection region. In this region just outside the main reflection region there is strong group velocity dispersion, causing different wavelengths of light to travel at different angles through the dielectric stack. As a consequence, different wavelength components of a polychromatic beam are separated as they pass through the device. The dielectric stack is preferably fabricated upon one or both sides of a transparent substrate so that the device can operate with light entering and/or exiting the substrate, eliminating the need for complicated antireflective coatings interfaced with the stack. Preferably, the device also comprises anti-reflective and reflective coatings to attain high optical efficiency and to increase spatial separation of the wavelengths of light, further reducing the size of the device. The device can also operate as a multiplexer by simply reversing the direction of the light. The device may be used for optical demultiplexing a polychromatic beam into spatially separated wavelength component beams by coupling the polychromatic beam into the multilayer dielectric stack, separating the polychromatic beam into component beams having distinct component wavelengths as the polychromatic beam passes through the multilayer dielectric stack, and coupling the component beams out of the multilayer dielectric stack. By reflecting the component beams from one or more mirrors in contact with the multilayer dielectric stack and/or substrate, further separation of the component beams may be produced as the component beams again pass through the multilayer dielectric stack. The method may also include transmitting the component beams and/or the polychromatic beam through antireflective material layers in contact with the multilayer dielectric stack and/or the substrate.

摘要： A transform spectrometer determines the spectrum of light based on the Talbot effect. Light to be analyzed is passed through a spatially periodic object, thereby generating a series of Talbot images. The intensities of these Talbot images at different optical distances from the spatially periodic object are then detected, and Fourier transformed to determine the spectrum of the light. Preferably, the detector comprises a spatial masking pattern such that the intensities detected are maximized at Talbot planes or at the midpoints between Talbot planes. In one embodiment, the optical distance between the spatially periodic object and the detector is changed in order to detect image intensities at different Talbot planes. In another embodiment, the detector and the spatially periodic object are positioned along a common optical axis at relative angle &thgr; such that different detector rows detect intensities at different Talbot planes. In yet another embodiment, the spatially periodic object is both a grating and a detector, and the Talbot images generated by the grating are reflected off a mirror back to the detector.

摘要： A network for multi-bit word parallel communication between optoelectronic chips on a two dimensional array of optical input and output channels carried on a single dimension of optical fibers. Each bit of a word is carried on a different wavelength and the multiple wavelengths carrying a word are wavelength multiplexed onto a single optical fiber. Multiple fibers can be joined into a one dimensional array of fibers. A transceiver for transmitting and receiving along the optical data channels comprises an array of modulators powered by individual wavelength light beams, either from individual monochromatic light sources and a light beam from a single broadband light source made to pass through a diffraction grating. The modulators are positioned so that each modulator reflects a different wavelength light beam, thereby providing multiple optical channels. Alternatively, multiple wavelengths are generated from CMOS integrated light sources. These multiple optical channels are then collimated and guided into one single mode fiber or multiple multimode fibers at its transmitting end. At the receiving end a diffraction grating is used to separate the distinct data channels by their individual wavelengths. The multiple wavelengths are then caused to fall on an array of optical detectors spaced according to the individual wavelengths to be detected. By constructing a one dimensional array of these fibers, a two dimensional array of optical data channels is realized. The size of the array is determined by the number of fibers and the number of distinct wavelengths combined in each fiber.
