A NEW APPROACH OF LONG DISTANCE ALL-OPTICAL SWITCHING MECHANISM BY INTERACTION BETWEEN TWO GAUSSIAN PULSES IN TRANSVERSE MODE PROPAGATED THROUGH AN OPTICAL WAVEGUIDE

摘要

In this communication we propose an analytical model of phase sensitive transverse interaction between two orthogonally polarized Gaussian pusles. To realize it we consider a Gaussian pulse propagating through an electro optic modulator. Using polarizer we first decompose it into two linearly orthogonal polarized waves. Then the orthogonal components of the pulses move through the optical fiber. By controlling the applied voltage across the modulator and controlling the ratio of length to width of the modulator we can change the phase relation between the pulses. With the method a switching at a very long distance can be organized in the optical fiber.
