ABSTRACT: The photovaractors for microwave photonic application were studied. The photovaractors were fabricated as a planar p-i-n or metal-semiconductor-metal (MSM) photodiodes placed in a pigtailed fiber optical module. The study of S11 parameters in the frequency range up to 3 GHz under illumination has shown that capacitances of p-i-n and MSM photodiodes strongly depend on the optical power. The capacitance variation of the photo-varactor diode under illumination is discussed.
