#331 Devices: electronic and photonic

In electronic semiconductor devices electron acts as an information carrier and the change in the input electrical signal (voltage or current) drives changes in the output current. In the photonic devices, where photon is an information carrier there is an interplay between light (photons) and electric current (electrons): current in – light out defines operation of the Light Emitting Diode (LED) while the opposite, light in – current out is a foundation of the solar cell operation.

 

I don’t mean to promote an oversimplifying picture of semiconductor device engineering, but the above pretty much sums up what active semiconductor devices are all about.
