Abstract: Described herein is a packaging approach that employs a remapping layer to maintain compatibility to different types of electronic chips while allowing chip designers to standardize the layout of the electrical interface of a photonic interposer. A remapping layer remaps the electrical interface of an electronic chip to the electrical interface of a photonic interposer. Remapping layers may be implemented in various ways, including for example as monolithic electronic interposers and/or as individual remapping chips. In some embodiments, to reduce manufacturing costs, remapping layers may be implemented using passive electronics (without transistors). Because remapping layers are significantly less costly to manufacture than photonic interposers, shifting the need to provide ad hoc electrical interfaces from the photonic interposer to the remapping layer enhances the applicability of photonic interposers in computational, telecom and datacom settings.

Abstract: Described herein are techniques for intra-chip communication within tiled photonic interposers. A photonic interposer may rely on a combination of photonic lanes and electric lanes. For example, a photonic interposer may comprise a photonic integrated circuit (PIC) lithographically patterned with an array of photonic tiles, each photonic tile comprising an on-chip communication unit. The array of photonic tiles is arranged in rows and columns. A plurality of electric lanes place the on-chip communication units of photonic tiles of different rows in electrical communication with one another. A plurality of photonic lanes place the on-chip communication units of photonic tiles of different columns in optical communication with one another.

Abstract: Photonic interposers that enable low-power, high-bandwidth inter-chip (e.g., board-level and/or rack-level) as well as intra-chip communication are described. Described herein are techniques, architectures and processes that improve upon the performance of conventional computers. Some embodiments provide photonic interposers that use photonic tiles, where each tile includes programmable photonic circuits that can be programmed based on the needs of a particular computer architecture. Some tiles are instantiations of a common template tile that are stitched together in a 1D or a 2D arrangement. Some embodiments described herein provide a programmable physical network designed to connect pairs of tiles together with photonic links.

The second sidewall may include a reflective surface formed thereon. The photodetector may be configured to receive an optical signal propagated in the waveguide, through the first sidewall and reflected from the reflective surface on the second sidewall.

A bonder which has the ability to precisely position the components in two dimensions can be utilized.

This information may be fed back to the bonder to control the precise alignment in the third dimension.

Abstract: An optical transmitter includes an external cavity laser array formed in a PLC, a trench-based detector array and an AWG. The external cavity laser is formed using an array of substantially similar laser gain blocks and an array of gratings formed in waveguides connected to the gain blocks. Each grating defines the output wavelength for its corresponding external cavity laser. Each detector of the detector array includes a coupler to cause a portion of a corresponding laser output signal of the laser array to propagate through a first sidewall of a trench and reflect off a second sidewall of the trench to a photodetector. In one embodiment, the photodetector outputs a signal indicative of the power level of the reflected signal, which a controller uses to control the laser array to equalize the power of the laser output signals.
