We investigate the adiabatic enhanced compression of ultrashort pulses from a distributed feedback laser operated at 1550 nm in fibres with slowly decreasing dispersion (FSDD). High-quality pulse compressions from 4.4 ps down to 1.1ps in a l00m FSDD and from 4.4ps down to 830fs in a 500m FSDD are obtained. The Raman self frequency shift of femtosecond pulses in the compression is observed. Theoretical analyses are in good agreement with experimental results. 展开更多

We built a pulse compressor using a comb-like dispersion-profiled fiber(CDPF).The CDPF consists of 12-segment fibers with the dispersion alternatively high and low.Using this compressor and a 17dBm Erbium-doped fiber amplifier,the 10GHz,12ps pulses generated from an actively mode-locked Er^(3+) doped fiber ring laser was compressed to~2ps without pedestal.We also show that compared with the high order soliton pulse compressor,the power efficiency can be doubled in supercontinuum generation by using the pump pulses compressed by this CDPF compressor. 展开更多

All-optical clock recovery by a two-section DFB laser with different injection wavelengths is demonstrated experimentally at 38.5 GHz.An optical clock with a root-mean-square timing jitter of 250 fs and an extinction ratio of 12.1 dB is obtained with 1551 nm injection.The timing jitter of the recovered clock is further investigated for various intensity ratios of the two DFB emission modes. 展开更多
