Schuller Lab at SPIE Optics and Photonics

Roark is representing the Schuller lab with exciting results on a new microLED architecture designed to simultaneously increase light extraction and directionality for air-side and substrate-side emission in GaN/InGaN devices. Additionally, our collaborator, Stephen Gee from SSLEEC, will be reporting on microcavity LEDs!
