Enhancement in microwave modulation efficiency of vertical cavity surface-emitting laser by optical feedback
Nemi Gavra, Valentina Ruseva, and Michael Rosenbluh
We investigate a versatile vertical cavity surface-emitting laser (VCSEL) with a slight optical feedback from a simple wedge positioned at a well determined distance from the VCSEL. We use such a laser in conjunction with a miniature Rb atomic cell to detect coherent population trapping (CPT) when t ... [Appl. Phys. Lett. 92, 221113 (2008)] published Fri Jun 6, 2008.
