摘要： A level-setting attenuator for generating an output signal having a predetermined optical power from an input optical signal having a varying power is disclosed. The level-setting attenuator includes a telecentric imaging device, a variable atttenuator, an optical power detector and control electronics. The telecentric imaging device collimates a received optical signal which is received and partially attenuated by the variable attenuator. In some embodiments, the variable attenuator generates an attenuated signal portion and an unattenuated signal portion. The attenuated signal is directed, by the variable attenuator, to an optical power detector operable to measure the power of the attenuated optical signal. The detector sends a signal indicative of the measurement to control electronics. The control electronics are operable to generate a control signal for controlling the attenuation of the unattenuated signal portion so that is has the predetermined power level. The unattenuated signal portion is coupled, via the telecentric imaging device, into an output fiber.

摘要： A device having an optical modulation region and a photodetection region formed on a single wafer, and methods for making the device, are disclosed. In one configuration, the device consists of an off-axis nonpolar substrate that has, on one side, a region suitable for modulating an optical signal. The other side of the substrate has a region suitable for photodetection. The region suitable for modulating an optical signal includes a movable layer suspended over the substrate. As the movable layer moves under an applied voltage, the reflectivity of the modulation region changes. The photodetection region consists of a plurality of III-V layers. In a second configuration, the device consists of a III-V substrate that has a region for photodetection disposed on one surface. A region for optical modulation is disposed on the photodetection region.

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.

摘要： A safe cordless telephone is provided for use in showers. The user-friendly cordless telephone can also be used when taking a bath or outside when it is raining. The dependable cordless comprises a special portable cordless handset with a water-resistant housing that provides a handset body. The handset body is made of an impact-resistant plastic capable of withstanding water pressure and is insulated to prevent electrical shock. A water-resistant antenna extends upwardly from the handset. A battery seal is positioned about the battery chamber to prevent water from entering into the battery chamber. An elastomeric rib is snugly positioned about the front and back of the handset to prevent water from entering into the interior of the handset and shorting the telephone circuitry. The earpiece and mouthpiece of the handset can also have water impermeable membranes to prevent water from passing into the earpiece and mouthpiece of the handset. The back of the handset can have discs or segments to enhance gripping of the handset and prevent slippage of the handset in a shower. The front of the handset can also have a thumb-engaging depression to facilitate gripping of the handset in a shower. The base unit is located away from the shower and has a base antenna and a battery charger, as well as other features.

摘要： An optical switching device and method for selectively optically connecting at least one input fiber in a fiber bundle to at least one output fiber in a fiber bundle. To perform the optical switching, a light directing mechanism is provided proximate a face of a fiber bundle that contains the input fiber. The light from the input fiber is directed toward the output fibers by varying the orientation of the light directing mechanism relative the face of the fiber bundle. The light directing mechanism thereby enables the light from the input fiber to be selectively directed to each of the output fibers. By selectively controlling the orientation of the light directing mechanism, the light from the input fiber can be scanned to any number of output fibers, thereby producing a 1.times.N optical switch.
