Lately, active research has been conducted in slowing down light pulses to the order of tens of meters per second or below. An interesting application would be an optical buffer for all optical routers, where solid state devices operating under room temperature are desired. In this paper, we investigate the possibility of such a device with a Ce:BaTiO3 crystal. Group velocity as slow as 2 mm/s is obtained in the two-wave coupling experiment. By modulating the angular-multiplexed pump beams in the experiment, we also demonstrate the modulation of the output waveform, which could be used to address the problem of pulse broadening that so far limits the application of room temperature slow light.
