Abstract
A semiconductor photonics device includes a plurality of grating couplers, each configured to couple a particular wavelength (or wavelength range) of an optical signal to a waveguide of the semiconductor photonics device. In some implementations, various implementations of optical signal splitters or filters described herein enable respective wavelengths (or respective wavelength ranges) to be passed to each of the grating couplers (while filtering out other wavelengths or other wavelength ranges), thereby enabling the grating couplers to each handle a respective wavelength (or respective wavelength range). This enables multiple wavelengths (or multiple wavelength ranges) to be distributed across multiple grating couplers, which may increase the bandwidth of the semiconductor photonics device relative to a semiconductor photonics device that includes only a single grating coupler.
