Outline of Research at the Start	We propose a novel hybrid cavity, in which a suitably-sized 2D materials flake is combined with a photonic crystal waveguide post-fabrication. Through this approach, we aim to demonstrate high Q cavity formation, low threshold optically excited lasing, and eventually electrically pumped lasing.
