Photon heterodyning

A heterodyne is a signal frequency that is created by combining or mixing two other frequencies using a signal processing technique called heterodyning, which was invented by Canadian inventor-engineer Reginald Fessenden. Heterodyning is used to shift signals from one frequency range into another, and is also … See more In 1901, Reginald Fessenden demonstrated a direct-conversion heterodyne receiver or beat receiver as a method of making continuous wave radiotelegraphy signals audible.

It is shown that the semi-classical theory of photon as the wave packet is the most suitable for the interpretation of “single photon” experiments, if only the value of length of photon would be corrected according to our proposal. Webphoton heterodyning. Recently, Ref. [12] reports an interferometer scheme using AOMs as the beam-splitter and the beam-combiner to observe the beating signal of single photons. However, the visibility of the interferometer in [12] is about 15%, which is not suitable for most efficiency sensitive quantum technology. Here we demonstrate an acousto- force from momentum
