我们研究了近红外通信光谱区[1.55 μm]的双折射液晶的光学非线性。折射率变化的原因是热折射率效应和指向矢轴重取向。用mW的激光功率在微米厚的染料掺杂双折射液晶薄膜中可以产生很大的折射率和几个π的相位调制。
We have studied the optical nonlinearities of nematic liquid crystals in the near IR communication spectral region [1.55 µm]. The origins of the refractive index changes are thermal indexing effect and director axis reorientations. Very large refractive index and phase modulation of several π's can be generated with mW laser power in micron thick dye-doped nematic liquid crystal films.
