摘要： Methods and systems for large silicon photonic interposers by stitching are disclosed and may include, in an optical communication system including a silicon photonic interposer, where the interposer includes a plurality of reticle sections: communicating an optical signal between two of the plurality of reticle sections utilizing a waveguide. The waveguide may include a taper region at a boundary between the two reticle sections, the taper region expanding an optical mode of the communicated optical signal prior to the boundary and narrowing the optical mode after the boundary. A continuous wave (CW) optical signal may be received in a first of the reticle sections from an optical source external to the interposer. The CW optical signal may be received in the interposer from an optical source assembly coupled to a grating coupler in the first of the reticle sections in the silicon photonic interposer.

摘要： A system for integrated power combiners is disclosed and may include receiving optical signals in input optical waveguides and phase-modulating the signals to configure a phase offset between signals received at a first optical coupler, where the first optical coupler may generate output signals having substantially equal optical powers. Output signals of the first optical coupler may be phase-modulated to configure a phase offset between signals received at a second optical coupler, which may generate an output signal having an optical power of essentially zero and a second output signal having a maximized optical power. Optical signals received by the input optical waveguides may be generated utilizing a polarization-splitting grating coupler to enable polarization-insensitive combining of optical signals. Optical power may be monitored using optical detectors. The monitoring of optical power may be used to determine a desired phase offset between the signals received at the first optical coupler.
