## Abstract Photomodulated reflectance (PR) studies are conducted on the wafer of a vertical‐cavity surface‐emitting laser (VCSEL) designed for oxygen sensing up to high temperatures. By varying the angle of incidence, the VCSEL cavity mode (CM) is tuned through the positions of two static PR featu
