Electrically tunable bandpass filter using solid-core photonic crystal fibers filled with multiple liquid crystals
Publication: Research - peer-review › Journal article – Annual report year: 2010
An electrically tunable bandpass filter is designed and fabricated by integrating two solid-core photonic crystal fibers filled with different liquid crystals in a double silicon v-groove assembly. By separately controlling the driving voltage of each liquid-crystal-filled section, both the short-wavelength edge and the long-wavelength edge of the bandpass filter are tuned individually or simultaneously with the response time in the millisecond range.
