Abstract: An optical interconnect circuit for transmitting data between two or more electronic chips. In an example embodiment, the optical interconnect circuit comprises two or more photonic chips, each of which is vertically stacked with the corresponding electronic chip such that compact optical modulators and/or photodetectors of the photonic chip are in close proximity to the data sources/sinks of the corresponding electronic chip. Multi-core optical fibers and vertical coupling structures are used to provide multiple optical connections between different photonic chips. Advantageously, the provided capability to place optical modulators close to the data sources and to place photodetectors close to the data sinks can be used to reduce the amount of required electrical wiring. Optical-waveguide connections to the multi-core fibers can be used to allow for high density of optical conduits without spatially constraining the placement of data sources and/or data sinks on the electronic chips.

Abstract: A system comprising an optical receiver for multi-wavelength-channel optical communication, an optical source of spontaneous emission light and a tunable optical filter connected to receive the light at an input. The tunable optical filter can have a filter spectrum with spectral passbands separated by spectral notches. The system also includes an optical fiber link connecting an output of the optical filter to the optical receiver for multi-wavelength-channel optical communication. The receiver can be configured to make a measurement indicative of an optical power level in at least one of the notches or to make measurements of optical power levels and at least one of the passbands and at least one of the notches in response to the optical source transmitting the filtered light to the optical fiber link. Another embodiment includes an apparatus comprising an optical test module including a source of spontaneous emission light and an optical filter connected to receive the spontaneous emission light from the source.
