Abstract

In this paper, we will outline the architectures of waveguide-integrated mid-infrared photodetectors, composed of black phosphorus-based van der Waals (vdW) heterostructures. The performed hybrid detector can detect broad spectral of light (λ: 3−4 μm) and show the feature of high operation speed (<10 MHz), high responsivity and long-term stability at room temperature. By exploiting this hybrid device platform, we further demonstrate that on-chip mid-infrared sources can be readily realized, showing great promise for on-chip sensing and spectroscopic applications.
