The analog fiber-optic link for Shanghai 65m radio telescope comprise PSI-1602 broadband microwave photonic link and 500 meters Corning optical cable. Performance measurement of the analog fiber-optic link is discussed. First, explained the measurement principles and methods of the PSI-1602 broadband microwave photonic link. Then, elaborated the group delay temperature coefficient measurement of Corning...
A novel technique for generating narrow-linewidth microwave or millimeter-wave signals is proposed. In this scheme, a delayed self-injected distributed Bragg reflector laser diode, which is tuned by a low-frequency square-wave voltage, is used to generate two correlated lightwaves simultaneously. Experiments show that the 10-dB linewidth of generated microwave signals is reduced from 147 MHz to 68...
