Abstract
An vertical cavity surface emitting laser feedback system is provided which has a vertical cavity surface emitting laser for emitting a specific amount of optical radiation. A portion of the optical radiation is received by a detection means which is used to generate a feedback signal that corresponds to the amount of optical radiation being emitted by the vertical cavity surface emitting laser.
