Abstract
Silicon-based photonic integrated circuits (PICs) operating in the mid-infrared wavelength range are presented. Firstly, it is shown that the operation of the SOI-based waveguide circuits can be pushed beyond the telecom window till a wavelength of 4 μm. Ge-on-Si based PICs are demonstrated for operation beyond 4 μm wavelength. Low-loss waveguides and integrated
spectrometers are reported for both the waveguide platforms. We also present our results on efficient thermo-optic phase shifters for germanium waveguide circuits. Related Research Topics
