Not all amplifiers are the same and there is a clear distinction made between the way their output stages operate. The main operating characteristics of an ideal amplifier are linearity, signal gain, efficiency and power output but in real world amplifiers there is always a trade off between the...

When light reaches the eye, the cornea and the lens act as amplifiers. Like a magnifying glass, they concentrate light onto the retina (the back of the eye) which, afterward, is processed by the brain as an image. Those three components of the human eye (cornea, lens and retina) are ...
[17] proposed a switch that performs switching of optical packets through a broadcast-and-select switching matrix and then re- amplification by Semiconductor Optical Amplifiers (SOAs). This switch splits the incoming optical packet into several ways corresponding to output ports, blocks those that ...
