Question

What is optical gain and optical loss in semiconductor physics?

Answer 1

Answer:

Optical gain is the most important requirement for the realization of asemiconductor laser because it describes the optical amplification in the semiconductor material. Thisoptical gain is due to stimulated emission associated with light emission created by recombination of electrons and holes.

Answer 2

•Optical gain in semiconductor lasers describes the optical amplification of the semiconductor material which is due to the stimulated emission associated with light emission created by recombination of electrons and holes.

•Optical losses is due to light which could have generated an electron-hole pair but it doesnot because the light is reflected from the front surface or not absorbed in the solar cell.
