Ultraslow light propagation in solid media

Published Jan 1, 2005• 0 citations

Abstract

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.

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.

Strong dispersion of the refraction index causes slow light propagation. We reported on such phenomenon induced by coherent population oscillations effect in Erbium-doped solids achieving group velocities as low as 2.7 m/s.

Observation of Ultraslow Group Velocity of Light in a Solid

Alexey V. Turukhin, Venkatapura S. Sudarshanam, M. S. Shahriar +2 more

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.

Transmission enhancement of ultraslow light in an atom shelved model of spectral hole burning solids

Byoung Seung HAM, Joonsung Hahn

We present transmission enhancement of ultraslow light in an inhomogeneously broadened spectral hole-burning solid medium by using precedent dummy light. The function of the dummy light is to burn a half-depth narrow spectral hole in an optically shelved solid system and to maintain the system optically transparent to the probe light, where the probe must experiences ultraslow group velocity due to the narrow spectral hole. The observed transmission increase is as high as 7 times compared with self-induced ultraslow light [J. Hahn and B. S. Ham, Opt. Express 16, 16723 (2008)], where the transmission enhancement is equivalent to 10(5) amplification considering an optical depth of d = 10.

First observation of ultraslow group velocity of light in a solid

Alexey V. Turukhin, Venkatapura S. Sudarshanam, J. A. Musser +2 more

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 microsecond(s) in a 3-mm thick, optically dense crystal of Pr doped Y2SiO5. Reduction of the group velocity is accomplished by using a sharp spectral feature in absorption and dispersion that is produced by resonance Raman excitation of a ground-state spin coherence. Potential applications of slow and stopped light for the highly efficient storage and recall of optical data are discussed.

Ultraslow and superluminal light propagation in room-temperature solids

Robert W. Boyd, Matthew S. Bigelow, Nick N. Lepeshkin +2 more

We have observed ultraslow (57 m/s) propagation in ruby and superluminal (800 m/s) propagation in alexandrite enabled by the process of coherent population oscillations. Various novel applications are allowed by the ability to exercise such control on the velocity of light.
