| Abstract(in English) | Ultra-small light modulators have been made by san dwitching polymer-dispersed liquid crystal (PDLC) between two ferrules with optical fibers. The device can modulate light independently of the state of polarization, because the PDLC becomes transparent or opaque when either a sufficient or no voltage is applied to the film. The PDLC was prepared by mixing and annealing prepolymer and nematic liquid crystal with large anisotropy. An optical fiber modulator using 30μm thick PDLC film had an extinction ratio of 8/1～33/1, an insersion loss of 1.3dB, and rise and decay times of 4ms at a wavelength of 1.3μm. |
