摘要： Described herein are optical fiber shuffle circuits designed to programmably interconnect any number of ports without having to rely on thousands of optical fibers or more. The optical fiber shuffle circuits developed by the inventors and described herein can be built into photonic interposers. Photonic interposers of the types described herein include, for example, semiconductor substrates patterned (photolithographically) with photonic integrated circuits such as waveguides, modulators, photodetectors, switches, couplers, etc., or any combination thereof.

摘要： Described herein are photonic communication platforms that permit use by multiple users in a secure way. A platform comprises a substrate, a first photonic circuit monolithically integrated with the substrate, and a second photonic circuit monolithically integrated with the substrate. The first photonic circuit is patterned with a first plurality of photonic modules, the photonic modules of the first plurality being copies of a common template photonic module The second photonic circuit is patterned with a second plurality of photonic modules, the photonic modules of the second plurality being copies of the common template photonic module. A photonic link couples the first photonic circuit to the second photonic circuit. A controller optically isolates the first photonic circuit from the second photonic circuit by optically interrupting the photonic link.

摘要： Provided herein are optical flow switches, and optical flow switch packages, implemented using photonic switches. The optical flow switch includes a network of photonic switches arranged between input and output ports of the optical flow switch. The network of photonic switches spans two or more reticles, and the two or more reticles may include photonic switching arrangements corresponding to repeated reticle masks or sets of reticle masks. The optical flow switch may be mounted to a glass substrate to form an optical flow switch package.

摘要： 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.
