HOW DOES COHERENT DETECTION WORK? Figure 1 shows a simple direct detection transmitter and receiver. The modulation technique is chosen so that decoding in the receiver can be done directly, with a minimum of signal processing. Intensity modulation with direct detection (IM-DD) works effectively up to data rates of 10 Gb/s (note that there is no “hard(More)
