Abstract

Photonic Crystal Surface Emitting Lasers (PCSELs) have emerged as a third-generation diode laser technology for high power high brightness high speed lasers with applications in LiDAR and 3D sensing, datacom and lasercom, photonic and quantum integrated circuits. In this talk, we report PCSEL performance trade-offs and challenges in power scaling, modal competition, and charge injection control. We will report the impact of electron block layers in the heterostructure design, the symmetry breaking strategy in the optical cavity design, and the regrowth/hybrid integration trade-offs. Linewidth and watts level experimental results will be presented and discussed.
