Abstract

By performing optical two-wave mixing in a liquid crystal light valve, we are able to slow down optical pulses to group velocities as slow as a few tenths of mm/s, corresponding to a very large group index. We present experiment and model of the slow light process occurring in liquid crystal light valves. The large group index corresponds to having a large sensitivity for phase variations, a property that can be used to increase the sensitivity of Fourier transform interferometer. We show that when a liquid crystal light valve is inserted in a Mach–Zehnder interferometer, the effect of frequency perturbations at the input of the system is amplified by a factor related to the group delay.
