Abstract: Various embodiments disclosed herein describe photonic switch. The controllable photonic switch may be configured with an asymmetry and different doping level that concurrently route two different wavelengths of light by wavelength-dependent phase shifters. In some instances, the controllable photonic switch includes a waveguide having an asymmetric cross-sectional shape. In other instances, the controllable photonic switch selectively route different wavelengths of light to different outputs of the controllable photonic switch.

Abstract: Embodiments are directed to optical measurement systems that utilize multiple emitters to emit light during a measurement, as well as methods of performing measurements using these optical measurement systems. The optical measurement systems may include a light generation assembly that is configured to generate light via a light source unit, and a photonic integrated circuit that includes a launch group having a plurality of emitters. Each of these emitters is optically coupled to the light generation assembly to receive light generated from the light generation assembly, and may emit this light from a surface of the photonic integrated circuit. The optical measurement system may perform a measurement in which the light generation assembly generates light and each of the plurality of emitters simultaneously emit light received from the light generation assembly.
