Abstract :
We demonstrate a compact millimeter wave signal generator based on a phase-modulated laser and a dual-band fiber Bragg grating (FBG). Two optical sidebands of a phase-modulated spectrum propagate through two transmission windows temporarily open in a chirped FBG (CFBG) by inducing localized temperature variations. The millimeter wave frequency is tuned by the separate adjustment of each temperature profile.
