Paper Abstract

The time response of optical switching properties of Sb thin films under focused laser pulses is investigated. The results show that the response course can be divided into onset, opening, and closing stages. Formulas for their lengths are given. The onset and opening times decrease with increasing pumping light power density. The closing time is about 150 ns. For optical memory, if the power density of the readout and recording lasers changes from 5×109 to 15×109 W/m2, the onset time changes from 2.5 to 0.30 μs, and the opening time is on the nanosecond scale.
