Temperature Effects on the Photovoltaic Spatial Solitons in Two-Photon Photorefractive Media
The characteristic of the photovoltaic spatial solitons in two-photon photorefractive media is influenced by the temperature of the media. The bright and dark spatial soliton solutions of the evolution equation of spatial solitions are related to the temperature. The intensity profile and the full-width at half maximum (FWHM) of photovoltaic spatial solitons in two-photon photorefractive media are dependent on the temperature of the media in the room temperature range. With the raising of the temperature of the two-photon photorefractive media, the photovoltaic spatial solitons with small intensity can be supported, moreover, the photovoltaic spatial solitons with small FWHM can be established under the large intensity case, and the photovoltaic spatial solitons with wider FWHM can be formed under the small intensity case. That is to say that the profiles of the photovoltaic spatial solitons can be controlled by the temperature, so as to form the steady photovoltaic spatial solitons in the two-photon photorefractive media.
