Femtosecond response time in a polarization-rotation switch using semiconductor-doped glasses.
A polarization-rotation switch is demonstrated that is based on semiconductor-doped glasses. The response time is shorter than 50 fs, and an on-off ratio of 38:1 could be obtained at a pulse fluence of 1.5 x 10(-6) J/cm(2), which corresponds to an intensity of 10 MW/cm(2).
