Abstract
In this paper, we propose a new approach for the generation of ultralow
jitter optical pulses using optoelectronic microwave oscillators. The short
pulses are obtained through time-lens soliton-assisted compression of
sinusoidally modulated prepulses, which are self-started from a conventional
single-loop optoelectronic oscillator. The inherent ultralow phase noise of
optoelectronic oscillators is converted into ultralow timing jitter for the
generated pulses. We provide a time-domain model for the slowly varying
amplitudes of the microwave and optical oscillations, and our analytical
study is confirmed by numerical simulations and experimental measurements.
We demonstrate the generation of 4.1 ps pulses along with a microwave whose
phase noise is $-$140 dBc/Hz at 10 kHz from the 10 GHz carrier, with
2.7fs jitter in the 1–10 kHz frequency
band.
