Described herein are wavelength division multiplexing (WDM) transceivers configured to support fast, bidirectional communication over optical channels. An optical transceiver comprises a transmitter, a receiver, an input/output (I/O) port and an optical interleaver. The transmitter comprises a first bus waveguide and a plurality of optical modulators coupled to the first bus waveguide, each of the optical modulators being resonant at a respective wavelengths in a first wavelength set. The receiver comprises a second bus waveguide and a plurality of optical filters coupled to the second bus waveguide, each of the optical filters being resonant at a respective wavelength in a second wavelength set. The (I/O) port is coupled to an optical channel. The optical interleaver is configured to selectively couple light having wavelengths in the first wavelength set from the first waveguide bus to the I/O port, and selectively couple light having wavelengths in the second wavelength set from the I/O port to the second bus waveguide.

Spectrally interleaved optical transceivers

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.
