Abstract :
In this paper, we demonstrate that generation of free carriers in the narrow bandgap layers of the semiconductor distributed Bragg reflector (DBR) can also be used for designing the SESAM with optical limiting function. This DBR can serve as a fast all-optical switching element. In conclusion, we have examined the possibility of using a nonlinear semiconductor mirror, whose reflectivity decreases with light intensity.
