Waveguide-Integrated Graphene-Colloidal-Quantum-Dots Photodetector with High Responsivity and Fast Response
We propose and demonstrate a graphene-CQD waveguide photodetector. It exhibited a measured responsivity of 2 A/W at 1550 nm, a fast response time of <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$\mathbf{3}\ \boldsymbol{\mu}\mathbf{s}$</tex>, and a low dark current of 7 nA.
