Mid-wave infrared (MWIR, 2-5 um) integrated photonics is an active area of research with the potential to miniaturize optical devices for many applications such as environmental monitoring, chemical sensing, and astronomical observations. However, the traditional Silicon-on-Insulator (SOI) material platform becomes absorbent above 3.5 um, so alternate materials and fabrication approaches are needed to enable photonic integrated circuits at longer wavelengths. This talk will summarize the development of an integrated photonic Germanium-on-Silicon platform for the 2-5 um wavelength range including demonstrations of waveguides and ring resonators, and designs for active device integration.
