Abstract
Optoelectronic device including integrated light emitting device and photodiode. The optoelectronic device includes a light emitting, device such as a vertical cavity surface emitting laser (VCSEL) or resonant cavity light emitting diode (RCLED). A photodiode is also included in the optoelectronic device. Between the light emitting device and the photodiode is a transition region. At least part of the transition region is shorted. A metal contact provides a contact to both the light emitting device and the photodiode.
