چکیده
With increasing interest and required features in dynamically reconfigurable network architectures [1], compact non-mechanical optical signal processors are in great demand to develop reliable, fast-reconfiguring, energy/space-efficient network elements such as dynamic add/drop multiplexers, dynamic optical routers and all-optical cross connects with signal regulation functionality. Liquid crystal technology has been drawing a lot of attention to as an option for all-optical signal processors because of its unique abilities to provide optical performance comparable to optomechanical devices, but with the reliability and efficiency of solid-state devices. In this paper, several optical signal processors, including optical switches, optical attenuators and optical gain equalizers, using liquid-crystal technologies, are discussed. The measurement results of optical performance are presented.

Abstract: In this paper, we aim to design and propose a novel structure for all-opticalhalf subtractor based on the photonic crystal. The structure includes two optical switches,one power splitter, and one power combiner. The optical switches are made of theresonant rings which use the nonlinear rods for dropping operation. The footprint of thedesigned structure is about...
متن کاملAnalysis of the Multireflection Effects in Compensated Liquid Crystal Devices
The effect of multiple internal reflections on the extinction ratio of perfectly compensated liquid crystal devices is studied. We find the previously unexplained wavelength dependence of light leakage in an ideally compensated device is caused by the interference of the internally reflected ordinary and extraordinary waves. While these effects have not been previously made clear, they can plac...
