Gain Measurements on Vertical Cavity Surface Emitting Laser Material Using Segmented Contact Technique

We report direct measurements of the optical gain profile for a vertical cavity surface emitting laser (VCSEL) epitaxial structure, by characterising the transverse electric (TE) in-plane net modal gain using the segmented contact method.
