Summary: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.
