Germanium on Silicon Integrated Photonics for the Mid-Wave Infrared
… and communications. This work develops low-loss waveguides, a passive component library, integrated modulators, laser integration design, and systems analysis for the 2-5 µm wavelength range. Low-loss waveguides are demonstrated with losses of 0.6-2.5 dB/cm without top cladding. A …

Low-Temperature Germanium Waveguides for Mid-Infrared Sensing Applications
… makes Ge-on-Si an effective platform for mid-IR waveguides. For back-end-of-line (BEOL) integration of waveguides in sensing applications, the thermal budget limits the temperature to below 450°C. In this work, we investigated the use of h-line exposure as a commercially viable, low-cost option …

Simulation and design optimization of wave propagation in heterogeneous materials
… one may be interested in the design of low-loss waveguides, invisibility cloaks, superlenses or light frequency filters. For acoustic applications one may consider the design of passive noise filters or sound beams. The physics governing the propagation of waves is well understood and …
