FDTD analysis of direct optical integration between SiNx waveguides and Ge/SiGe multiple quantum wells on graded buffer for low-voltage optical modulators around the O-band wavelength

FDTD analysis of direct optical integration between SiNx waveguides and Ge/SiGe multiple quantum wells on graded buffer for low-voltage optical modulators around the O-band wavelength

We focus on investigating the possibility to achieve a direct butt coupling integration of SiNx passive waveguides with germanium/silicon–germanium (Ge/SiGe) multiple quantum wells (MQWs) on a thick graded buffer platform using 3D finite-difference time-domain simulation. Despite the promising poten...
