Abstract
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.
