Abstract

We experimentally propose a technique to demonstrate an optical slow-light system using the two-wave mixing (TWM) process in a photorefractive (PR) crystal at room temperature. This technique uses the refractive index variation that occurs in the PR material at room temperature. In this paper, we show that the time delay and the bandwidth of the transmitted pulses can be easily tuned by varying both laser beam intensities and the widths of the input pulses. In addition, time delays of short light pulses are observed with modest pulse distortions at the output of the PR crystal using a pulsed laser at the nanosecond regime.
