(A)1.55-μm波长范围超连续谱(SC)的光波控制研究：1.55-μm波长范围的超连续谱(SC)的光波控制：通过数值分析研究了1.55-μm波长范围的超连续谱(SC)的相位。(B)1-μm波长范围的超连续谱(SC)的光波控制研究：最近，报道了通过浸入重水(D2O)或特殊设计的光子晶体光纤(PCF)的锥形光纤(TF)传输的光脉冲，由于光纤的色散特性在1000 nm附近具有低的色散特性，因此可以在超连续谱(SC)产生宽的fl光谱。研究了在低色散光纤中产生的SC脉冲的光谱强度和相位分布。结果表明，群速度色散(GVD)分布在1000 nm附近具有极值和零色散分布的高非线性光子晶体光纤在短光纤长度上非常适合于关注相位分布的应用；此外，选择并购买了空间光调制器空间相位调制器(SLM)，并制作了用于组装光波控制系统的器件。

This research was executed about the following :(a) Investigation for optical wave control of supercontinuum (SC) near a 1.55-μm wavelength range:Optical wave control of Supercontinuum (SC) spectrum near a 1.55-μm wavelength range:Supercontinuum (SC) spectrum phases of 1.55-μm near a wavelength range was investigated by numerical analysis.(b) Investigation for optical wave control of supercontinuum (SC) near a 1-μm wavelength range:Recently, optical pulses propagating through a tapered fiber (TF) immersed in heavy water (D2O) or photonic crystal fi ber (PCF) of a special design were reported to yield a broad and fl at supercontinuum (SC) spectrum because the fi ber dispersion characteristics are of low dispersion around 1000 nm. This study was undertaken to investigate spectral intensities and phase distributions of SC pulses generated in low-dispersion fi bers. Results show that highly nonlinear PCF with group velocity dispersion (GVD) distributions having an extremum value and zero dispersion around 1000 nm is useful at short fiber length for applications in which the phase distribution is a concern.Moreover, the spatial light modulator space phase modulator (SLM) was selected and purchased, and the device for assembling a optical wave control system was fabricated.
