All-optical method of conducting long-distance switching by proper use of an electro-optic Pockels material and a nonlinear optical waveguide

Abstract

An optical soliton pulse can be effectively used as an information-carrying signal in a nonlinear optical fiber medium. We propose an analytical model for phase-sensitive switching by the use of two mutually orthogonal polarized Gaussian pulses. To realize it we consider a Gaussian pulse first propagating through an electro-optic modulator. The orthogonal components of the pulse are introduced into the optical fiber. By controlling the applied voltage across the modulator we can change the phase relation between the components. By this method, switching at a very long distance can be implemented in the optical fiber.

An all-optical remote controlled X-Nor logic using soliton pulse

“…Owing to this replacement, high speed communication will be achieved as well as many other operational activities, including three dimensional image and data processing, neural networking, real time operations, memory storage capacity of the computer, data carrying capacity, computer computer interaction and interfacing, channel base and channel free operation, local to wide area networking etc. will be implemented very successfully [1,2,6,7,9,[10][11][12][13][14] . In information communication systems, the optical soliton pulses is are better accepted than ordinary optical pulses as the optical soliton pulses offers some special and very crucial advantages over ordinary optical pulses.…”

Using modified Mach-Zehnder interferometer to get better nonlinear correction term of an isotropic nonlinear material

“…Nonlinear material (NLM) is being more and more promising as it has a tremendous applicational role in photonic switching systems and many other optical devices [1,2] . Mach-Zehnder interferometer (MZI) is also regarded as a very potential optical device for many interferometric purposes, e.g., measurement of optical characteristics and developing optical logic circuits, etc.…”
