Observations of single pulse slow light in a persistent spectral hole-burning crystal

Abstract

We investigate a self induced ultraslow group delay as long as 40 μs in a persistent spectral hole-burning crystal. The ultraslow light has potential application to on-demand all-optical information processing such as on-demand buffer memory.

Observations of self-induced ultraslow light in a persistent spectral hole burning medium

Joonsung Hahn, Byoung Seung HAM

We present observations of self induced ultraslow light in a persistent spectral hole-burning rare-earth doped crystal. The observed group delay (velocity) is as long as 40 micros (75 m/s), which is comparable to that obtained using electromagnetically induced transparency or coherent population oscillations. We analyze the observed ultraslow light as a function of frequency detuning, light intensity, and atom population (oscillator strength). The present observation of ultraslow light in a persistent spectral hole-burning medium gives potentials to all-optical information processing such as on-demand all-optical buffer memories.

Slow Light with Persistent Spectral Hole Burning

We consider short pulse propagating in a thin slab waveguide of optically dense persistent hole burning medium. Considerable slowing of group velocity occurs if narrow hole is created in advance in the inhomogeneous absorption spectrum.

Slow light by persistent spectral hole burning

Alexander Rebane

We survey pulse reshaping by propagation through narrow spectral transmission features in optically dense, inhomogeneously broadened persistent spectral hole burning medium. Trade-off between maximum pulse delay and pulse shape distortion is analyzed. Results are comared to delays based on spectral gratings and time-space holograms.

Ultraslow light propagation in a solid

Fan Bao-Hua, Zhang Yun-Dong, Yuan Ping +1 more

With the spectral hole-burning effect resulting from coherent population oscillation in the homogenously broadened material, the ultraslow light propagation phenomenon with the group velocity as slow as 27.55±0.05m/s at room temperature in a ruby crystal is observed. And the group velocity in ruby crystal depends on the amplitude modulation frequency, the power of laser beam and the orientation of the crystal lattice. Lower frequency or higher power leads to slower group velocity.

Ultraslow light propagation in solid media

Fan Bao

The basic theories underlying the reduction of the group velocity of light are introduced and methods for achieving ultraslow light propagation are discussed. The phenomenon of spectral hole-burning in homogeneously broadened media and the experimental slowing of light in ruby are described. We discuss the significance of such research for science and applications.

Observation of Ultraslow Group Velocity of Light in a Solid

We report ultraslow group velocities of light in a solid. Light speeds as slow as 45 m/s were observed, corresponding to a group delay of 66 ms in a 3-mm thick crystal. Reduction of the group velocity is accomplished by using a sharp spectral feature in absorption and dispersion, produced by a Raman excited spin coherence in an optically dense Pr doped Y2SiO5 crystal.
