Modulator
A modulator is a device that changes the amplitude, phase, or polarization of a continuous waveform. In other words, it alters the intensity of the output light.
Photodetector
A photodetector is a device that detects the presence of photons. It measures how much power is reflected from the surface of the detector.
Amplifier
An amplifier amplifies the input signal before passing it onto the next stage.
DE Multiplexer
A demultiplexed separates incoming signals based on their wavelengths.
Multiplexer
