Optical heterodyne detection — is an important special case of heterodyne detection. In heterodyne detection, a signal of interest at some frequency is non linearly mixed with a reference local oscillator (LO) that is set at a close by frequency. The desired outcome is the… … Wikipedia
Optical downconverter — (ODC) is an example of a non linear optical process, in which two beams of light of different frequencies ω1 and ω2 interact, creating microwave with frequency ω3 = ω1 − ω2. It is a generalization of microwave. In the latter, ω1 = ω2, both of… … Wikipedia
