#Semiconductoropticalamplifiers work similarly to a laser. The structure is almost the same as two particularly produced pieces of semiconductor material on top of each other, with another material in between them forming the “active layer”.
An electrical current is set running through the pattern in order to excite electrons, which can then fall back to the non-excited area event and give out photons.
