Abstract
An all-optical frequency-upconversion based on fractional talbot effect is experimentally reported. The 2.5-Gb/s baseband signal carried on 10GHz pulse trains is upconverted to 40GHz millimeter wave after 18.49km transmission via repetition frequency multiplication of pulse trains. The phase noise of the 40GHz is as well as -92dBc/Hz at 10kHz frequency detuning. This scheme can operate in 60GHz band by employing the appropriate fiber length based on fractional talbot effect.
