摘要： An optical communication system for transmitting multiple optical beams, each at a different wavelength is disclosed. The optical communication system includes a laser array having multiple laser transmitters transmitting multiple optical beams, each at a different wavelength. The optical communication system further includes a diffraction grating optically coupled to the laser array, the diffraction grating diffracting each of the optical beams at a substantially equal diffraction angle to form a combined optical beam. The combined beam is then focused into an optical communication media.

摘要： One or more single mode waveguide devices are fiber coupled such that signals to an optical element affect the coupling of the waveguide device to an optical fiber. A number of systems and methods are disclosed to adjust the coupling of the waveguide device to the optical fiber. These include dithering the tunable optical element at different frequencies along differing axes and using a lock-in technique to derive an error signal for each degree of motion, using a beamsplitter to form a secondary image of the focused beam on a position-sensitive detector, the use of a chiseled fiber to generate reflections from the angled facets, using an additional laser for a secondary image, or obtaining a secondary image from an angled fiber or a parasitic reflection.

摘要： A wavelength tunable laser includes a distributed feedback (DFB) array with first and second DFB laser diodes that generate first and second beams of light in first and second wavelength ranges. A microelectromechanical (MEMS) optical element selectively couples one of the first and second beams of light from the DFB laser array into an optical waveguide. The MEMS optical element includes a collimating lens and a thermal or electrostatic MEMS actuator for moving the collimating lens to select the one of the first and second beams of light. A focusing lens is located between the collimating lens and the optical waveguide. Alternately, the MEMS optical element includes a fixed collimating lens that collimates the first and second beams of light, a mirror, and a MEMS actuator for tilting the mirror to select the one of the first and second beams of light.

摘要： Optical pumping arrangements are provided for the broadband or multiple wavelength pumping of optical sources. Sources may be based on Raman gain media and may use multiple output couplers to couple out different wavelength ranges. Cascaded Raman resonator (CRR) configurations may also be used. Overlapping resonators at different wavelengths may be configured to share gain media, and may have separate portions in separate optical paths. Attenuation filters may also be used that are matched to the gain profile of a gain medium, to flatten the gain spectrum and allow equalization of gain to different output wavelengths. In one embodiment, polarization maintaining fiber is used to develop resonant conditions at different wavelengths in different polarization states. Wideband output gratings may be substituted for narrowband gratings to provide CRR configurations with a broader output band. Broadband amplification may also be provided by using a laser source operating in coherence collapse. The multiple wavelength pumping lends itself to a pumping arrangement in which sources at different wavelengths are combined into separate transmission/gain media such as the different fibers of an optical fiber cable.

摘要： By moving a substrate relative to a shadow mask in a reactive ion etching system, we are able to precisely tailor the thickness of critical layers. To minimize disturbing the plasma, all the mechanical components are kept below the anode. The system is highly reproducible, and can be programmed to yield arbitrary vertical profiles along one horizontal axis. Using silicon-on-insulator substrates, the resonance wavelength was modified as a function of position with better than 1 nm control in the vertical dimension. This technique should prove useful for optical devices where the thickness of the layers controls the device characteristics.

摘要： Optically coupling two or more optical transceiver integrated circuits (OTRIC) using OTRIC-on-substrate assemblies is disclosed. The optical transceiver integrated circuits may be attached to different substrates, where the substrates may allow the passage of optical signals to and from the optical transceiver integrated circuits. The OTRIC-on-substrate assemblies may comprise one or more optoelectronic device arrays, lenses and mirrors, mounts, and optical transmission medium. The optical transmission medium may be free space or and optical fiber. An optical coupling mechanism may be used in conjunction with the OTRIC-on-substrate assemblies to link optical signals between the optical transceiver integrated circuits.
