We report measurements and traceability of terahertz wavelength and frequency. Terahertz frequency comb is used for traceability of terahertz frequency. Frequency of a stable source is precisely ...

We present a novel radio-frequency (RF) photonic phase shifter based on wavelength dependence of Brillouin frequency shift. A continuous and full phase shift up to 360° at 18 GHz is achieved when the ...
