چکیده
A photonic crystal fiber was selectively infiltrated only two of the air holes near core with liquid crystal. The selective infiltration caused geometric asymmetry and created high birefringence. Because asymmetry, response to varying electric field is concerned direction. Sagnac interferometer set investigate tuning characteristics fiber. effective refractive-indices varies due reorientation molecules. highest sensitivity 1.12 nm/V (504 nm/kV/mm) range 7 nm when direction parallel connecting line holes. time studied. device can be utilized as voltage sensors, electro-optical modulators filters.

Performance of Sagnac Interferometer with Loops Made of PCF and PANDA Fibers
Optical fiber Sagnac loop as a interferometer (SLI), is a useful component utilized in devices and systems of optical technology [1,2]. As of today, several components based on SLI, have been designed for applications of wavelength division multiplexing (WDM) filters and optical sensors, using conventional and photonic crystal fibers [3-6]. In an SLI, two interfering waves in an optical fiber l...
متن کاملSingle-photon Sagnac interferometer
We present the first experimental demonstration of the optical Sagnac effect at the single-photon level. Using a high quality guided-wave heralded singlephoton source at 1550 nm and a fibre optics setup, we obtain an interference pattern with net visibilities up to (99.2 ± 0.4%). On the basis of this high visibility and the compactness of the setup, the interest of such a system for fibre optic...
متن کاملUltrafast gating using a nonlinear Sagnac interferometer
Ultrafast gating is a powerful technique for applications such as time resolved spectroscopy [ 1-3 ], imaging through scattering media [4-7 ], or nonlinear optics [ 8 ]. Several methods have been used, each of which has its own limitations. The Kerr shutter [ 3 ] is extremely fast (femtosecond) but requires high peak power lasers. It has a maximum transmission of approximately 10 percent, and i...
متن کاملContinuous phase amplification with a Sagnac interferometer
We describe a phase-amplification technique using a Sagnac interferometer. We monitor the relative phase between two paths of a precisely misaligned interferometer by measuring the average position of a split-Gaussian mode in the dark port. Although we monitor only the dark port, we show that the signal varies linearly with phase and that we can obtain similar sensitivity to balanced homodyne d...
متن کاملSagnac interferometer for gravitational-wave detection.
We have investigated a zero-area Sagnac interferometer as a broad band gravitational-wave detector. Frequency response measurements of a laboratory-scale interferometer are in excellent agreement with theory. The measured contrast ratio, 0.996, is insensitive to induced birefringence, laser-frequency variation, arm imbalance, and dc mirror displacement. A near shot-noise-limited phase sensitivi...
