摘要： In a hybrid integrated module, a semiconductor die is mechanically coupled face-to-face to an integrated device in which the substrate has been removed. For example, the integrated circuit may include an optical device fabricated on a silicon-on-insulator (SOI) wafer in which the backside silicon handler has been completely removed, thereby facilitating improved device performance and highly efficient thermal tuning of the operating wavelength of the optical device. Moreover, the semiconductor die may be a VLSI chip that provides power, and serves as a mechanical handler and/or an electrical driver. The thermal tuning efficiency of the substrateless optical device may be enhanced by over 100× relative to an optical device with an intact substrate, and by 5× relative to an optical device in which the substrate has only been removed in proximity to the optical device.

摘要： One embodiment of the present invention provides a system that facilitates adjusting the wavelengths of lasers via temperature control. This system includes a chip with an active face upon which active circuitry and signal pads reside. A thermal-control mechanism provides localized thermal control of two lasers mounted upon the active face of the chip. By individually controlling the temperature of the lasers, the thermal-control mechanism controls the wavelengths emitted by each respective laser. By creating a temperature gradient that causes a temperature difference between two or more lasers, the system can cause the lasers to emit different wavelengths.

摘要： A multi-chip module (MCM) is described. This MCM includes at least two substrates that are remateably mechanically coupled by positive and negative features on facing surfaces of the substrates. These positive and negative features mate with each other. In particular, a positive feature may mate with a given pair of negative features, which includes negative features on each of the substrates. Furthermore, at least one of the negative features in the given pair may include a hard magnetic material, and the positive feature and the other negative feature in the given pair may include a soft magnetic material that provide a flux-return path to the hard magnetic material. In this way, the hard magnetic material may facilitate the remateable mechanical coupling of the substrates.

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： Embodiments of a method for assembling a multi-chip module (MCM) are described. During this method, a fluid that includes coupling elements is applied to a surface of a base plate in the MCM. Then, at least some of the coupling elements are positioned into negative features on the surface of the base plate using fluidic assembly. Note that a given coupling element selects a given negative feature using chemical-based selection and/or geometry-based selection. Next, the fluid and excess coupling elements (which reside in regions outside of the negative features on the surface) are removed.

摘要： A multi-chip module (MCM) that includes at least two substrates, having facing surfaces, which are mechanically coupled by a set of coupling elements having a reflow characteristic, is described. One of the two substrates includes another set of coupling elements having another reflow characteristic, which is different than the reflow characteristic. These different reflow characteristics of the sets of coupling elements allow different temperature profiles to be used when bonding the two substrates to each other than when bonding the one of the two substrates to a carrier. For example, the temperature profiles may have different peak temperatures and/or different durations from one another. These reflow characteristics may facilitate low-cost, high-yield assembly and alignment of the substrates in the MCM, and may allow temperature-sensitive components to be included in the MCM.

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.
