Optoelectronic parametric amplification in a microstrip ring resonator on GaAs substrate Academic Article uri icon

abstract

  • Nonlinear interaction between an optically modulated RF input and a microwave LO (local oscillator) in a nonlinear microstrip ring resonator on a semi-insulating GaAs (gallium arsenide) substrate is investigated. When the capacitive reactance of the detector is modulated, a parametric amplification effect of the mixer occurs. In this device structure, a parametric amplification gain of 10 dB without applied bias in the RF signal is obtained. This microwave optoelectronic mixer can be used in fiber-optic communication links.
