台阶层数的增加，可增加红外抗反射入射波长和入射角的范围。
When the phase level was increased, the incident wavelength and the incident Angle range of the infrared anti-reflection were also increased.
然而，当入射波长处于零色散波长区时，三阶色散将影响孤子传输的稳定性。
However, third-order dispersion (TOD) will affect the stability of soliton propagation when the wavelength of signal is in the zero dispersion wavelength regions.
周期与入射波长同数量级的体积布喇格光栅的衍射效率，与入射线偏振光的偏振方向有关。
Diffraction efficiency of volume Bragg grating, whose period is in the same order as the incident wavelength, is related to the polarization direction of the incident linear polarized beam.
