摘要： An integrated circuit that includes an optical waveguide defined in a semiconductor layer is described. In this integrated circuit, light is coupled between the optical waveguide and an optical modulator, which is disposed on the optical waveguide, using 3-dimensional (3-D) taper structures that are proximate to the ends of the optical modulator. The cross-sectional areas of these 3-D taper structures transition, over a distance, from that of the optical waveguide (distal from the optical modulator) to that of optical modulator (proximate to the ends of the optical modulator). In this way, a spatial extent of an optical mode in the optical waveguide and a spatial extent of the optical mode in the optical modulator may be approximately matched to reduce the optical loss when the light is coupled to or from the optical modulator.

摘要： A multi-chip module (MCM) is described. This MCM includes two substrates having facing surfaces. Disposed on a surface of a first of these substrates, there is an optical waveguide, having an eigenmode in the plane of the surface, and an optical coupler, which redirects optical signals to and/or from the optical waveguide and a direction normal to the surface. Furthermore, disposed on a surface of a second of the substrates, which faces the surface of the first substrate, and which overlaps the optical coupler, there is an optoelectronic device. This optoelectronic device, which has an eigenmode in a direction perpendicular to the surface of the second substrate, selectively receives or provides the optical signal to and/or from the optical coupler. For example, the selective receiving or providing may be controlled by selectively applying a potential to the quantum-well device, thereby changing the optical properties of the optoelectronic device.

摘要： An optical device that includes multiple optical modulators having actual operating wavelengths at a given temperature is described. Because of differences between the actual operating wavelengths and target operating wavelengths of the optical modulators, heating elements may be used to thermally tune the optical modulators so that the actual operating wavelengths match corresponding carrier wavelengths in a set of optical signals. Furthermore, control logic in the optical device may assign the optical modulators to the corresponding carrier wavelengths based at least on differences between the carrier wavelengths and the actual operating wavelengths, thereby reducing an average thermal tuning energy associated with the heating elements.

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.

摘要： An optical device that includes multiple optical modulators having target operating wavelengths that are distributed over a band of wavelengths and actual operating wavelengths is described. For example, the target operating wavelengths of adjacent optical modulators may be separated by a wavelength increment. Moreover, because of differences between the actual operating wavelengths and the target operating wavelengths of the optical modulators, tuning elements may be used to tune the optical modulators so that the actual operating wavelengths match corresponding carrier wavelengths in a set of optical signals. Furthermore, control logic in the optical device may assign the optical modulators to the corresponding carrier wavelengths based at least on differences between the carrier wavelengths and the actual operating wavelengths, thereby reducing an average tuning energy associated with the tuning elements.

摘要： Embodiments of a system are described. This system includes an array of chip modules (CMs) that are configured to communicate data signals with each other via optical communication. In a given CM module, optical signal paths, such as waveguides, are routed in the same way as in the other CMs in the array.

摘要： An optical source includes a set of N light sources that provide a corresponding set of N optical signals having N carrier wavelengths. These optical signals are combined into a seed optical signal and transported to a substrate using an optical fiber. This substrate includes a set of K optical amplifiers that amplify the seed optical signal and provide a set of M output optical signals on a corresponding set of M output optical waveguides (where M is less than K). In this way, a total power of the set of M output optical signals may be significantly larger than that of the seed optical signal, thereby ensuring that a majority of a power efficiency of the optical source is associated with power efficiencies of the set of K optical amplifiers instead of power efficiencies of the set of N light sources.
