摘要: We investigate theoretically the temperature effects on the evolution of both bright and dark screening-photovoltaic optical spatial solitons in biased photovoltaic-photorefractive crystals in the case of neglecting the diffusion process. For a stable bright or dark screening-photovoltaic soliton originally formed in a crystal at a given temperature, when the crystal temperature changes, it will evolve into another stable screening-photovoltaic soliton if the change is quite small, whereas it will become unstable or break down if the temperature change is large enough. The spatial shape of a stable screening-photovoltaic soliton can be reshaped by appropriately adjusting the crystal temperature.
