Abstract :
Nonlinear optical-microwave mixing is performed in an uniplanar CPW-to-slotline ring resonator on a semi-insulating GaAs substrate, in which a Schottky photodetector is monolithically integrated as a coupling gap. The parametric amplification effect of the mixer occurs when the capacitive reactance of the detector is modulated. In this structure, a parametric amplification gain of 20 dB, without the applied bias in the radio frequency (RF) signal, is obtained. This microwave optoelectronic mixer can be used in fiber-optic communication links
