Abstract
We report on the possibilities of graphene channel FET (G-FET) as a photonic frequency double-mixing conversion device for future fully coherent access network systems. A 112.5-GHz RF signal whose amplitude was coded with a 5-GHz rectangular signal was input to the gate, concurrently a 1.58-μm wavelength photomixed dual CW laser beam having a beat frequency of 87.5 GHz was incident to the FET, generating the local (LO) signal. The RF and LO signals were mixed to reproduce the down-converted 5-GHz signal onto the 25-GHz intermediate frequency (IF) signal successfully.
