LIGHT-EMITTING DIODES (LEDS) WITH MONOLITHICALLY-INTEGRATED PHOTODETECTORS FOR IN SITU REAL-TIME INTENSITY MONITORING

摘要

Devices directed to light-emitting diode (LED) lighting applications and methods of fabricating the same are provided. A device can include an LED integrated with a photodetector on the same semiconductor platform, such that the photocurrent generated by the photodetector can be used to monitor the optical output of the LED, which is located adjacent to the photodetector. Compact, robust, and reliable photodetectors capable of monitoring LED emission via a low-cost approach are provided.
