Abstract
We demonstrate an all optical up-conversion system by injecting low bitrates baseband OOK signal directly into a conventional Fabry-Pérot laser diode (FP-LD). Radio frequency (RF) carrier is generated due to period-one (P1) oscillation state of nonlinear dynamics system (NDS) in the FP-LD with the injection of external optical signal. No extra high speed and expensive local oscillator is required for the up-conversion. Based on this approach, we experimentally achieved the up-conversion of 2Â Gbps RZ-OOK baseband signal to 12Â GHz and 14.28Â GHz RF carriers, and 2.5Â Gbps NRZ-OOK baseband signal to 10Â GHz, 18.2Â GHz and 20.88Â GHz RF carriers respectively. The obtained 20.88Â GHz RF carriers have a signal to side mode suppression ratio of 29Â dB, and phase noise of â84.2Â dBc/Hz@10Â kHz.
