We design and fabricate a compact tunable and rotatable polarization controller using liquid crystal photonic band gap fibers. The electrically and thermally induced phase shift in the Poincaré sphere and corresponding birefringence change are measured. The direction of the electric field is managed by connecting four electrodes in different electrode configurations, and the thermal tunability is controlled by on-chip heaters. According to the results, a quarter-wave plate and a half-wave plate working in the wavelength range of 1520–1600 nm are experimentally demonstrated.

“…All types of LCs can be used: nematic [101], electroclinic [102], ferroelectric [103] and nano-PDLC [62]. However, smectics and nano-PDLCs are preferred due to switching times better than conventional nematics.…”

“…Among several types of PCs, a rotatable waveplate using a liquid crystal (LC) [4][5][6][7] is very attractive compared to other devices employing electro-optic materials such as PLZT [8] or LiNbO 3 [9] because LC devices have merits of low power consumption, relatively low driving voltage, compactness, and the capability of endless control of evolving PS. However, nematic LC-based PCs suffers from slow response (on the order of 10 msec).…”
