Abstract :
Optical control and sub-harmonic-injection-locking of a 60 GHz millimeter-wave oscillator using InP-based HEMTs are reported. The oscillation frequency locking by the injection of several order sub-harmonic signals was clearly observed. In addition, the modulation of the frequency-locked 60 GHz signals by the illumination of a tightly focused laser beam with intensity modulation was also demonstrated. This oscillator can lead to a key device for the base station in millimeter-wave wireless systems with optical fiber links.
