Single Sheet Lasers for Attojoule Optoelectronics
Abstract
The objective of this project is investigate laser scaling towards extreme energy efficiency. A range of photonic crystal cavities were proposed and investigated. Optically pumped room temperature lasers were achieved with low lasing threshold and high directional beam, based both on exfoliated and large area CVD WS2 materials on heterostructure photonic crystal cavities. Detailed investigations were carried out on the laser cavities and lasing characteristics, including spectral outputs, polarization, optical beam divergence angle, and lifetime measurements.
