The death of DUSEL, or a serious delay, would haveeffects that would ripple across the scientific community, saysMilind Diwan, a physicist at Brookhaven National Laboratory inUpton, New York.
Reflection spectrum, group time delay and group time delayripple are analyzed by the method of transformation matrix.
用传输矩阵法分析反射谱、时延曲线和群时延抖动。

Through these measurement and analyse, bring forward the method to reduce the chirp FBG device's group delayripple, phase ripple and optimize it's PMD and PDL.
