چکیده
A 2×2 high contrast ratio optical switch composed of holographic optical switching elements is presented. This switch consists of two electro-optic halfwave plates, four layers of holographic gratings, two dielectric substrates, and one spacer. The contrast ratio can be higher than 54 dB. The contrast ratio improvement of this device is the same as a dilated optical switch. Key-words: Holographic optical switching element, Optical switch, Optical interconnection network, Photonic switching, Contrast ratio, Crosstalk, Signal-to-noise ratio, Polarization beam splitter.

Optimization of Bistability in Nonlinear Chalcogenide Fiber Bragg Grating for All Optical Switch and Memory Applications
We solve the coupled mode equations governing the chalcogenide nonlinear fiber Bragg gratings (FBGs) numerically, and obtain the bistability characteristics. The characteristics of the chalcogenide nonlinear FBGs such as: switching threshold intensity, bistability interval and on-off switching ratio are studied. The effects of FBG length and its third order nonlinear refractive index on FBG cha...

We propose a novel two state and all-optical controllable switch using DIT, Kerr effect and interaction between quantum dots (QD) and quantum electrodynamics cavity (CQED). The two state and all-optical controllable switch is coupled to photonic waveguide from a rapid nonlinear environment (photonic crystal) and CQED. We consider the nano-crystal are doped to crystal photonic cavity as a 4-leve...

This paper demonstrates the design of an Arrayed Waveguide Gratings (AWG) based optical switch. In the design both physical and network layer analysis is performed. The physical layer power and noise analysis is done to obtain Bit Error Rate (BER). This has been found that at the higher bit rates, BER is not affected with number of buffer modules. Network layer analysis is done to obtain perfor...
