ABSTRACT:
A VCSEL (113) having a first and a second stack of distributed Bragg reflectors (120, 116) and an active region (118) defining a light generating and emitting path. A layer (104) of semiconductor material is formed on the second stack (116) so as to intersect the light path and a first electrode (106) and a second electrode (108) are disposed on the layer (104) to form a metal-semiconductor-metal photodetector (102). The metal-semiconductor-metal photodetector (102) absorbs some of the light emitted by the VCSEL (113) and provides an indication of the light output intensity, which indication may be used to control the VCSEL (113).
