Simulations of liquid-crystal Fabry–Perot etalons by an improved 4Ã4 matrix method
نویسندگان
چکیده
The optical performances of a liquid crystal ~LC! Fabry–Perot ~FP! etalon in various configurations were simulated by a faster 434 matrix method. Results show that the FP with a 90° twisted nematic LC is polarization insensitive if the applied voltage exceeds ;3X of the Freedericksz transition threshold. This method can well depict the transmission spectra of the FP cavity and, therefore, is useful for optimizing the FP tunable filters for telecommunications. © 2003 American Institute of Physics. @DOI: 10.1063/1.1542652#

Micromachined three-dimensional tunable Fabry-Perot etalons
We report on novel three-dimensional tunable Fabry-Perot etalons fabricated by surface micromachining technique. The Fabry-Perot etalons are tuned by rotation or translation movements. For the Fabry-Perot etalon tuned by rotational movement, the Fabry-Perot etalon is integrated with a rotational stage and the effective light path distance is adjusted by rotating the stage. The transmission peak...
متن کاملInterferometry and laser control with solid Fabry-Perot etalons.
The use and analysis of solid Fabry-Perot etalons for interferometry and laser control are discussed and supported with experimental data. Low angle scattering is found to be an important factor influencing finesse and peak transmission. Thermal tuning sensitivity and wedge-angle control with thermal gradients are analyzed and illustrated. Control of laser oscillations using a solid-state etalo...
متن کاملNovel tunable liquid crystal Fabry-Perot filters for Fiber-Optical system
Tunable filters with a wide tunable range that cover the whole C-band , or L-band, or both, have been found wide applications in fiber optical communication system, mainly in three domain: tunable laser, wavelength division multiplexing systems (WDM), and channel monitoring. Due to the growing demand in bit-rate and number of channels in WDM system, tunable narrow band pass filters are required...
متن کاملDBR, Sub-wavelength grating, and Photonic crystal slab Fabry-Perot cavity design using phase analysis by FDTD.
We demonstrate a Finite-Difference Time-Domain (FDTD) phase methodology to estimate resonant wavelengths in Fabry-Perot (FP) cavity structures. We validate the phase method in a conventional Vertical-Cavity Surface-Emitting Laser (VCSEL) structure using a transfer-matrix method, and compare results with a FDTD reflectance method. We extend this approach to a Sub-Wavelength Grating (SWG) and a P...
متن کاملFabry Perot etalon with polymer cholesteric liquid-crystal mirrors.
We present what we believe to be the first implementation of a Fabry-Perot (FP) etalon using polymer cholesteric liquid-crystal mirrors. These polymer mirrors have each been fabricated onto a single substrate, which allows the FP cavity spacing to be only a few micrometers wide. For the experimental results presented, cavity lengths of 13.8 and 7.6 microm yield near-infrared free spectral range...
