Abstract

In this talk, we demonstrate a black phosphorus/molybdenum ditelluride heterostructure photodetector, integrated with a silicon-on insulator (SOI) waveguide. The performed heterostructure photodetector exhibits high responsivity in the midinfrared spectral region. Moreover, our developed hybrid detector can exhibit ultrafast rise and fall time. Such features suggest its usefulness to real-time on-chip sensing applications.
