Abstract: Aspects of the present application are related to an Er-doped waveguide amplifier (EDWA) structure integrated in an uncooled silicon photonic transceiver and methods for fabricating the same. In some embodiments, the structure comprises three layers of waveguides: silicon, silicon nitride and Er-doped dielectric. The three layers of waveguides are integrated with an uncooled 980-nm pump laser. In some embodiments, the Er-doped dielectric waveguides are fully etched.

Abstract: Optical coherent receiver arrays are described. The optical coherent receiver arrays include an integrated array of photodetectors separated by integrated mirrors which may cause interference of received free space optical and local oscillator signals. The mirrors may serve as splitters, helping to align the received signal and local oscillator to cause interference. The photodetectors of the optical coherent receiver array may be electrically coupled in various manners to read out the signals. The optical coherent receiver array may be implemented in an optical coherence tomography (OCT) imaging system in some embodiments.

Abstract: Disclosed herein are techniques, methods, structures and apparatus that provide a silicon photonics multicarrier optical transceiver wherein both the transmitter and receiver are integrated on a single silicon chip and which generates a plurality of carriers through the effect of an on-chip modulator, amplifies the optical power of the carriers through the effect of an off-chip amplifier, and generates M orthogonal sets of carriers through the effect of an on-chip basis former.
