Abstract
This paper describes a 20 GHz experimental coupled optoelectronic oscillator based on the concept of active self mode-locking (regenerative mode locking) a Nd:YVO/sub 4//MgO:LiNbO/sub 3/ multi mode microchip laser. A millimeter wave signal is generated by beating the multiple longitudinal modes of the laser in a photo detector. In principle, the oscillator can be designed to operate to beyond 100 GHz. An important feature of this COEO is the absence of external narrowband RF filters and E/O modulators. The laser acts as an extremely narrowband filter in the microwave domain, which enables selection of one oscillation line. A phase noise of -102 dBc/Hz at 10 KHz offset was measured (limited by the noise floor of the analyzer used for the measurement). Lower phase noise is expected with optimization of the system and equipment.
