Frequency-domain Hong–Ou–Mandel interference
Nature Photonics, 2016By using a single-photon frequency converter based on quasi-phase-matched LiNbO3, frequency-domain Hong–Ou–Mandel interference is demonstrated between a heralded single photon at 780 nm and a weak laser pulse at 1,522 nm in a single spatial mode. Hong–Ou–

Finite fields are amenable to Fourier transform-like operations which move the data through orthogonal domains in a very similar manner to which the Fourier transform provides a doorway between time and frequency. Just as the Fourier transform extracts pure sine waves from time domain data, the equivalent operation on a finite field extracts features ...

For frequency-domain FLIM (fluorescence lifetime imaging microscopy), the amplitude of the excitation light is modulated repetitively at high frequency (HF). Radio frequencies between 1 and 200 MHz are nominal and chosen in order for the fluorescence response (nanoseconds) to be sensitive to the frequency of repetition/modulation.

By frequency-domain analysis one generally means an analysis of systems based on representing input and output as linear combinations of sinusoidal functions. Such an analysis is most useful for studying the steady-state behavior of linear and time-invariant systems.

Signals which are sufficiently stationary permit highly efficient coding in the frequency domain. Such signals include speech signals such as sustained vowels and prolonged fricatives, as well as generic audio signals such as music and mixed material. The main components of frequency domain coding methods include windowing, a time-frequency transform ...
