Single Sheet Lasers for Attojoule Optoelectronics
Abstract
The objective is to reach for the ultimate limit of miniaturized laser by demonstrating ultra-fast, zero-threshold lasing from a single atomic layer, based on high-mobility electron transport, mechanical agility, and efficient light emission in 2D material heterostructures, coupled with unconventional high quality factor (Q) optical cavities. Optically pumped sheet lasers will be first demonstrated based on BN/WSe2/BN (for visible) and black phosphorus (BP, for IR) heterostructures in critically-coupled photonic crystal cavities. Electrically pumped sheet lasers will then be demonstrated based on 2D/III-V nanowire heterostructures for side-coupled one-dimensional ohmic contacts to lateral WSe2 junctions. Various nano-scale gain and cavity structures in scaling towards attojoule lasers will also be explored.
