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.

Optocoupler with multiple photodetectors and improved feedback control of LED

An optoelectronic device comprises a light source, a generally coplanarly disposed detector, the detector receiving light from the light source, a light conductive inner encapsulate molded around the light source and the detector, an opaque light reflective outer encapsulate molded around and interfaced with a surface of the light conductive inner encapsulate, and a lens disposed above, and in a light path between, the light source and the detector.
