摘要
利用1.5ps高峰值功率脉冲泵浦色散位移光纤(DSF)得到的超连续(SC)谱实验结果:大于泵浦波长一侧的20dB带宽大于266.8nm,其中200nm范围内不平坦度<±2dB,1690～1780nm的不平坦度<±0.25dB;小于泵浦波长一侧的10dB带宽232nm,其中145nm范围内不平坦度<±2dB,1306nm～1368nm的不平坦度<±0.25dB。利用F P滤波器进行谱切片,在大于泵浦波长一侧和小于泵浦波长一侧分别得到顶部平坦的间隔2.52nm的95和57个波长输出。
Ultra-broadband supercontinuum (SC) is generated from a dispersion-shifted fiber (DSF) with 1.5 ps pump pulses. More than 266.8 nm 20 dB bandwidth spectrum longer than pump wavelength was obtained with ±2 dB spectral uniformity over 200 nm, where uniformity<±0.25 dB is achieved from 1690 - 1780 nm. While on the opposite side, 232 nm 10 dB bandwidth was also obtained with ±2 dB spectral uniformity over 145 nm, where uniformity <±0.25 dB is achieved from 1306 - 1368 nm. 95 and 57 channels with 2.52 nm spacing are carved out respectively from each side of the zero wavelength by using F-P filter.
