Abstract
A vertical-cavity surface-emitting laser for near-field illumination of an eye includes a semiconductor substrate, a first reflector, a mesa region, a first electrical contact, and a second electrical contact. The first reflector is disposed on a first side of the semiconductor substrate and the mesa region is disposed on the first reflector. The mesa region includes a second reflector and an active region, where the mesa region is configured to generate a diverging infrared beam. The first electrical contact is disposed on a second side of the semiconductor substrate, opposite the first side, for electrically coupling to the first reflector. The second electrical contact is also disposed on the second side of the semiconductor substrate for electrically coupling to the second reflector.
