Description |
This work provides a detailed numerical analysis on the optimized compression of a dual frequency beat signal to generate a spectrally-enriched short-duration pulse train at 10 and 40 GHz frequencies. The effect of pre-chirping the beat signal on its compression characteristics using a dispersion imbalanced nonlinear optical loop mirror (DI-NOLM) is studied in detail. The output pulse quality is characterized by the shape of the pulse, peak-to-pedestal ratio, spectral content of the pulse and the energy contained in the pulse. It is found that suitable pre-chirping of the beat signal results in better shaping characteristics with significant pedestal suppression. The suitability of the shaped picosecond pulses for further spectral enrichment and the possibility of multi-wavelength generation are also studied.
