| Abstract: | This paper makes semiconductors for an example ,the analysis model of the optical injecting and the change in refractive index of semiconductor induced by photo carrier is presented. This model is helpful on research total internal reflection type all optical switch. We get the refractive index distribution in the semiconductor versus light intensity in the direction of controlling light. And we get the thresholds of the controlling light (0.8μm) in the optically controlled optical switch at wavelength of 1.55μm and 1.31μm. |
