Abstract :
A simple and novel design for power monitoring, integrated in a VCSEL, is presented. A Schottky photodiode, placed close to the VCSEL, enables delivery of a photocurrent of several hundred muA from the lateral emitted light, throughout the whole light-current characteristics. It is shown that the Schottky contact significantly reduces the parasitic current in the cavity
