Waveplate, planar lightwave circuit incorporating the waveplate, and method of making an optical device. The waveplate is formed of a mesogen-containing polymer film having a backbone and sidechains containing mesogen groups. The waveplate may be formed by producing a mesogen-containing polymer film having a nonzero birefringence of suitable dimensions for insertion into a planar lightwave circuit. The waveplate may be so inserted into an optical circuit of a planar lightwave circuit so that an optical signal traversing the waveplate is changed, for instance, to have two polarization states.
波片、结合波片的平面光波电路以及制造光学器件的方法。该波片由含有基干和侧链的介质基团的聚合物薄膜形成。可以通过制备具有适当尺寸的非零双折射率的介质基团聚合物薄膜来形成波片,并将其插入平面光波电路的光学电路中,使通过波片的光信号发生变化,例如具有两种极化状态。
