Abstract
We present here experimental investigations of 2D material integrated with large area laterally confined heterostructure photonic crystal (PC) cavities. Both exfoliated and CVD synthesized WS2 materials have been investigated. Room temperature lasing was achieved for both material systems, with narrow spectral linewidth and highly directional emission. Multi-wavelength lasing was achieved through high yield transfer printing of large area CVD WS2 material onto photonic crystal cavity arrays. The scaling challenges of gain and laser cavities will also be discussed with the ultimate goal of attojoule lasers.
