Abstract: 

Future large-scale integrated photonic system demands materials and devices at atomic scales with virtually zero-energy consumption. Over the years, we have been working on a wide range of semiconductor materials towards compact nano-scale lasers, sensors, and bio-compactible photonic components. In this talk, we will report some recent advances on buried tunnel junction based quantum well lasers on silicon, photonic crystal cavity integrated single sheet lasers, and flexible/bio-compactible optical sensors. The potentials and challenges associated with crystalline semiconductor nanomembranes and monolayer 2D materials will also be discussed.
