用一低通滤波器和施密特触发器排除高频噪声脉冲。
Removing high frequency noise pulses by a low-pass filter and Schmitt-trigger.
结果表明：类噪声脉冲的带宽随着腔内净色散的增加而增加，并在腔内净色散为微正时达到最大值。
Results show that the spectral bandwidth of noise-like pulse will increase as the net cavity GVD increases and attains maximum when the GVD is slightly positive.
这些微型设备具备探测非常微弱的光脉冲、并且以前所未有的带宽将它们放大、同时使额外产生的不必要的噪声最小化的能力。
These tiny devices are capable of detecting very weak pulses of light and amplifying them with unprecedented bandwidth and minimal addition of unwanted noise.
