Switchable polarization-independent liquid-crystal Fabry-Perot filter.

چکیده
A new approach to a polarization-independent twisted liquid-crystal (LC) structure, where phase difference between orthogonal eigenmodes is tuned to be an integer multiple of 2pi, is demonstrated with a numerical model. For select wavelengths, polarization-independent operation can be achieved by tuning the twist rate and thickness of the LC cavity. Applications can be found in polarization- independent switches and field sequential wavelength selection devices.

Novel 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 کاملSimulations of liquid-crystal Fabry–Perot etalons by an improved 4Ã4 matrix method
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 us...
متن کاملAsymmetric tunable Fabry-Perot cavity using switchable polymer stabilized cholesteric liquid crystal optical Bragg mirror
Optical properties of an asymmetric Fabry-Perot (FP) cavity interferometer made up of a conventional metallic mirror and a polymer stabilized cholesteric liquid crystal (PSCLC) Bragg mirror have been investigated. The first FP cavity design comprises a gold mirror, an iso-tropic layer made up of the polymer glue, a quarter wave plate to convert the input linearly polarized modes into the circul...
متن کاملSwitchable circular-to-point converter based on holographic polymer-dispersed liquid-crystal technology.
We demonstrate the use of a switchable circular-to-point converter (SCPC) device based on holographic polymer-dispersed liquid-crystal technology for application in lidar detection and optical telecommunication. A SCPC device converts the Fabry-Perot ring pattern into a single point or an array of points, while an external electrical field on the SCPC deactivates the conversion. Stacking differ...

A novel wavelength-switchable single-longitudinal-mode (SLM) dual-wavelength erbium-doped fiber laser (EDFL) implemented based on a sigma architecture that is composed of a ring loop and a linear standing wave arm is experimentally demonstrated. Gain competition that prevents stable dual-wavelength oscillation is effectively suppressed by placing the gain medium in the standing-wave arm and by ...
