摘要： A waveguide (10) is provided having a two-dimensional optical wavelength Bragg grating (20) embedded within a semiconductor laser medium (16). More particularly, the waveguide (10) includes an active region (16) sandwiched between n-doped and p-doped cladding layers (14, 22). The two-dimensional Bragg grating (20) is formed in the active region (16). Upper and lower electrodes (24, 26) are defined on opposite sides of the cladding layers (14, 22) to complete the waveguide structure (10). The two-dimensional grating (20) provides simultaneous frequency selective feedback for mode control in both the longitudinal and lateral directions.

摘要： An electroabsorptive modulator (EAM) for providing RF modulation of optical inputs signals. The EAM is formed as a semiconductor waveguide on a semiconductor substrate with an optical input port and an optical output port and electrical contacts for connection to the RF input. The configuration of the waveguide portion of the EAM is optimized to provide a modal match with the particular optical device to which the EAM is to be connected, for example, an optical fiber. By optimizing the modal match between the EAM and the optical device to which the EAM is connected, the optical insertion losses are minimized thereby improving the overall performance of the optical system. The device is formed from a plurality of quantum wells selected to compensate for the increased mode field dimensions.

摘要： MSM-photodetectors are produced using implanted n-type Si and interdigitated electrodes deposited on the implanted surface. The implantation process decreases the carrier lifetime by several orders of magnitude. By implanting silicon with fluorine or oxygen, the bandwidth is increased relatively to unimplanted MSM photodetectors. Exemplary implanted photodetectors exhibited 3-dB bandwidths which were faster by an order of magnitude compared to their unimplanted counterparts. The detectors are thus compatible with multi-gigabit per second operation and monolithic integration with silicon electronics.
