摘要： A multi-chip module (MCM) includes a stack of chips that are coupled using optical interconnects. On a first surface of a middle chip in the stack, there are: a first optical coupler, an optical waveguide, which is coupled to the first optical coupler, and a second optical coupler, which is coupled to the optical waveguide. The first optical coupler redirects an optical signal from the optical waveguide to a first direction (which is not in the plane of the first surface), or from the first direction to the optical waveguide. The second optical coupler redirects the optical signal from the optical waveguide to a second direction (which is not in the plane of the first surface), or from the second direction to the optical waveguide. An optical path associated with the second direction passes through an opening in a substrate in the middle chip.

摘要： An optical multiplexer/demultiplexer is described. In this optical multiplexer/demultiplexer, multiple coupled-waveguide grating devices are optically coupled to a bus optical waveguide. A given coupled-waveguide grating device has a band-pass filter characteristic that encompasses multiple optical channels, thereby providing coarse optical filtering. Moreover, the optical multiplexer/demultiplexer includes multiple add/drop filters (such as ring resonators) that optically couple to the coupled-waveguide grating devices. A given add/drop filter has a filter bandwidth corresponding to a given optical channel, thereby providing fine optical filtering. Furthermore, the band-pass filter characteristic of the given coupled-waveguide grating device is approximately equal to or less than a free spectral range (FSR) of the given add/drop filter.

摘要： During operation of an electro-absorption modulator, an optical signal is conveyed, using an optical waveguide in the electro-absorption modulator, to a semiconductor layer that substantially fills a gap between two portions of the optical waveguide. Then, the optical signal is electro-absorption modulated by selectively applying a voltage to electrodes that produces an electric field, approximately perpendicular to the midline of the optical waveguide, in the semiconductor layer. These electrodes are coupled to the edges of the semiconductor layer at the periphery along the width of the semiconductor layer by intervening layers. Furthermore, the intervening layers include a material that has a lower index of refraction than the semiconductor layer, and a lower optical absorption than the electrodes.

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 with a high thermal resistance to the surrounding external environment and a low thermal resistance to a localized heater. In particular, the thermal resistances associated with thermal dissipation paths from a heater in the optical device to an external environment via electrodes and via the substrate are increased, while the thermal resistance between the optical waveguide and the heater is decreased.

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.

摘要： In a multiple-wavelength laser source, a multiple-mode laser outputs a set of wavelengths in a range of wavelengths onto an optical waveguide, where a spacing between adjacent wavelengths in the set of wavelengths is smaller than a width of channels in an optical link. Furthermore, a set of ring-resonator filters in the multiple-wavelength laser source, which are optically coupled to the optical waveguide, output corresponding subsets of the set of wavelengths for use in the optical link based on free spectral ranges and quality factors of the set of ring-resonator filters. These subsets may include one or more groups of wavelengths, with another spacing between adjacent groups of wavelengths that is larger than the width of the given channel in the optical link. In addition, the one or more groups of wavelengths may include one or more wavelengths, with the spacing between adjacent wavelengths in the given group of wavelengths.

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 using two semiconductor layers (such as silicon), one of which includes a heater and the other includes a thermally tunable optical waveguide. Spatially separating these two functions in the optical device results in more efficient heat transfer between the heater and the optical waveguide, reduced heat transfer to the surroundings, and reduced optical losses in the optical waveguide relative to existing silicon-based optical devices.

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.
