| Abstract: | A photonic approach for measuring microwave frequency over a wide bandwidth is proposed.An optic group delay line composed of several magneto-optical switches and a 1.6-km single-mode fiber is used as a tunable dispersive medium in the measurement setup.A minimum frequency accuracy of 80 MHz in the range of 1-20 GHz is achieved experimentally. |
