Abstract
Various embodiments of methods and devices are provided for an optocoupler comprising a layer of dielectric optically semi-reflective and transmissive material disposed between an LED and a first photodetector located above an upper surface of the layer, and a second photodetector located beneath the lower surface of the layer. The layer reflects a first portion of light generated by the LED towards the first photodetector to generate LED feedback control signals, and transmits a second portion of light generated by the LED through the layer for detection by the second photodetector to generate isolated output signals.
