Abstract
We have developed an all-fiber system which we use to demonstrate slow and fast light based on electromagnetically induced transparency in a 20 meter acetylene-filled photonic microcell. Using this system, 30 ns pulses of probe light were delayed and advanced by up to 5 ns and 1 ns respectively. The delay/advance is tunable through the probe detuning and the coupling Rabi frequency. Through optimization of experimental parameters such as acetylene pressure, coupling laser power and decoherence rates it is shown that a pulse delay of 30 ns/m is possible. Limitations imposed on the fiber length by resonance group velocity dispersion and spectral reshaping are also discussed. In addition to optical buffering, we suggest a slow-light based fiber optical gyroscope with an enhanced signal-to-noise ratio of ~ 92.
