Photon heterodyning
WebPhoton statistics and squeezing properties of a free-electron laser. S. Rai, S. Chopra. Physics. 1984. It is shown that the field emitted by a free-electron laser (FEL) in the low-gain regime exhibits antibunching over a wide range, for an initial Poisson distribution of probability amplitudes.

WebThe noise from tomographical homodyning is compared to that from heterodyning, for those operators that can be measured in both ways. It turns out that for some operators homodyning is better than heterodyning when the mean photon number is sufficiently small. Finally, the robustness of the method to additive phase-insensitive noise is analyzed. 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. Fessenden's receiver did not see much application … See more Heterodyning, also called frequency conversion, is used very widely in communications engineering to generate new frequencies and … See more • Electroencephalography • Homodyne • Transverter • Intermodulation – a problem with strong higher-order terms produced in some non-linear mixers See more Heterodyning is based on the trigonometric identity: The product on the … See more • Hogan, John V.
