Effects of temperature on the interaction of two-photon photorefractive sreening-photovoltaic bright spatial solitons

Abstract

Abstract:

In order to obtain the effect of temperature on the interactions of screening-photovoltaic bright spatial solitons in based two-photon photovoltaic photorefractive media,taking the two mutually coherent optical beam as the input wave,the beam propagation equation is solved numerically under different temperature. the result shows that the interaction of two in-phase solitons still have fusions along with temperature varying in the room temperature range. With the raising of the temperature of media to 350K, two in-phase solitons will fuse a solitary wave. With the varying of the temperature, the repulsions of two out-of–phase solitons are increasing. The repulsions and the energy transferring will are increasing with the varying of the temperature for the -phase-difference solitons. Two solitons will crash in the interactions process when the varying is great.
