摘要： An optical source includes semiconductor optical amplifiers, with a semiconductor other than silicon, which provide an optical gain medium. Moreover, a photonic chip in the optical source, which is optically coupled to the semiconductor optical amplifiers, includes ring resonators that selectively pass corresponding optical signals having carrier wavelengths provided by the semiconductor optical amplifiers, where a given ring resonator and a reflector on one of the semiconductor optical amplifier defines an optical cavity, and the ring resonators have different radii with associated resonance wavelengths corresponding to the carrier wavelengths. Furthermore, the photonic chip includes a shared ring resonator, optically coupled to the ring resonators, that selectively filters the optical signals, where the shared ring resonator has a different radius than the radii of the ring resonators with an associated resonance wavelength, and a free-spectral range of the shared ring resonator defines a spacing between the carrier wavelengths in the optical signal.

摘要： A method for manufacturing an electro-optically coupled switch in accordance with the present invention requires a sequential reconfiguration of a layer of semiconductor material. To begin, a base member is created wherein the semiconductor layer is positioned on a layer of insulator material with the insulator material positioned between the semiconductor layer and a semiconductor substrate. In sequence, with a first etch, the semiconductor layer is etched to create waveguides on opposite sides of a slot. In a second etch, the slot is deepened to expose the layer of insulator material in the slot. With a third contact pad doping process, pads can be positioned on top of the layer of insulator material for electrical contact with the respective waveguides. Metal contacts can then be placed on the contact pads, the slot can be filled with an electro-optical polymer and, if needed, the polymer can be poled.

摘要： Embodiments of an optical device, an array of optical devices, and a technique for fabricating the optical device or the array are described. This optical device is implemented on a substrate (such as silicon), and includes a thermally tunable optical waveguide that has good thermal isolation from its surroundings. In particular, a portion of a semiconductor in the optical device, which includes the optical waveguide, is free standing above a gap between the semiconductor layer and the substrate. By reducing the thermal coupling between the optical waveguide and the external environment, the optical device can be thermally tuned with significantly less power consumption.
