title: RF up/down-conversion based on optically injection-locked VCSEL.
abstract: All-optical radio frequency conversion is proposed by directly modulated optically injection-locked vertical-cavity surface-emitting lasers. The enhancement effect of second order products of RF signals by OIL technique is analyzed based on reflection-mode OIL model. Simulation results show that high injection ratio and large wavelength detuning of OIL condition lead to a high RF conversion gain. Compared with free running condition, more than 20 dB RF conversion gain enhancement is achieved in the simulation. The experimental results of the RF conversion gain improvement (+ 18 dB) by OIL show excellent agreement with our simulation results. The spurious free dynamic range improvement (+ 15 dB) of conversion signals by OIL is also experimentally demonstrated.
