TLDR
A novel configuration for four-wave mixing (FWM) is proposed that offers the remarkable feature of inherently separating the FWM wave from the input pump and signal waves and suppressing their background amplified stimulated emission without optical filtering.Abstract:
A novel configuration for four-wave mixing (FWM) is proposed that offers the remarkable feature of inherently separating the FWM wave from the input pump and signal waves and suppressing their background amplified stimulated emission without optical filtering. In the proposed configuration, an optical parametric loop mirror, two counterpropagating FWM waves generated in a Sagnac interferometer interfere with a relative phase difference that is introduced deliberately. FWM frequency-conversion experiments in a polarization-maintaining fiber achieved more than 35 dB of input-wave suppression against the FWM wave.read more

TL;DR: In this paper, a dispersion-flattened dispersion imbalanced nonlinear optical loop mirror is used to smooth the spectrum and reduce the pedestal of tunable femtosecond solitons generated via pulse compression in a dispersive-flanked dispersion decreasing fiber, and transform-limited pulses with durations less than 210 fs and peak-to-pedestal ratios greater than 40 dB are obtained over a wavelength range of 32 nm at a repetition rate of 10 GHz.
