Output power enhancement in photonic-based RF generation by optical pulse compression with a dispersion managed highly-nonlinear fiber

In this manuscript, we propose to use optical pulse compression in a dispersion managed fiber (DMF) with highly nonlinear fiber to enhance the output power in photonic-based 100-GHz RF generation. Even though the average dispersion is zero, RF gain of more than 5.0 dB can be obtained with moderate optical power to the DMF. Using four-sectioned DMF with zero average dispersion, we found the possibility of near octave-band operation in RF frequency.
