High Performance Electrically‐Injected InGaN Microdisk Lasers through Simultaneous Enhancement of Optical Confinement and Overlap Factor (Laser Photonics Rev. 18(8)/2024)
Year: 2024
Type: article
Abstract: Electrically-Injected InGaN Microdisk Lasers High Q, room-temperature lasing in InGaN microdisk lasers under electrical injection is achieved through a thin-film structure enhanced by a metallic undercut, which substantially improves optical confinement and overlap factor. Detailed analysis using near-field optical spectroscopy reveals strain relaxation near the edge plays a crucial role in reducing the Quantum Confined Stark Effect. This improvement in quantum efficiency has significant implications for the enhancement of lasing performance.
