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.

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: 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: An assembly comprising first and second electronic devices and an optical coupling device that optically couples an optical waveguide on the first electronic device to an optical waveguide on the second electronic device. In this way, optical proximity communication between the devices is possible. The electronic devices may be integrated circuit chips. The first optical waveguide is positioned relative to the optical coupling device to direct an optical signal to the optical coupling device. Further, the second optical waveguide is positioned relative to the optical coupling device to receive the optical signal, which is directed from the optical coupling device to the second optical waveguide. Thus, the optical coupling device optically couples the first optical waveguide to the second optical waveguide.

摘要: An MCM may include a single optical routing layer that provides point-to-point connectivity among N chips in the MCM, such as all-to-all connectivity or full-mesh point-to-point connectivity. Moreover, the optical routing layer may include: N optical waveguides optically coupled to the N chips and a cyclic de-multiplexer, optically coupled to the N optical waveguides, that routes optical signals among the N optical waveguides without optical-waveguide crossing in the optical routing layer. For example, the cyclic de-multiplexer may include: an array-waveguide-grating (AWG) wavelength router and/or an echelle-grating wavelength router.

摘要: Using silicon photonic components that support a single polarization, the output of an optical receiver is independent of the polarization of an optical signal. In particular, using a polarization-diversity technique, the two orthogonal polarizations in a single-mode optical fiber are split in two and processed independently. For example, the two optical signals are provided by a polarizing splitting grating coupler. Subsequently, a wavelength channel in the two optical signals is selected using a wavelength-selective filter (for example, using a ring resonator or an echelle grating) and combined at an optical detector (such as a photo-detector) to achieve polarization-independent operation.
