Observation of Ultraslow Group Velocity of Light in a Solid
نویسندگان
چکیده
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 μs 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.

Observation of ultraslow and stored light pulses in a solid.
We report ultraslow group velocities of light in an optically dense crystal of Pr doped Y2SiO5. Light speeds as slow as 45 m/s were observed, corresponding to a group delay of 66 micros. Deceleration and "stopping" or trapping of the light pulse was also observed. These reductions of the group velocity are accomplished by using a sharp spectral feature in absorption and dispersion that is produ...
متن کاملQuantum Information Storage with Slow and Stopped Light
This essay describes the phenomena where the group velocity of light is reduced to ultraslow speeds, and even stopped in atomic gases. The coherent coupling of photons to atomic spin excitations in the gases through Electromagnetically Induced Transparency (EIT) is discussed, and experimental observation is presented as evidence of the phenomena with specific focus on the emergence of excited s...
متن کاملObservation of ultraslow light propagation in a ruby crystal at room temperature.
We have observed slow light propagation with a group velocity as low as 57.5+/-0.5 m/s at room temperature in a ruby crystal. A quantum coherence effect, coherent population oscillations, produces a very narrow spectral "hole" in the homogeneously broadened absorption profile of ruby. The resulting rapid spectral variation of the refractive index leads to a large value of the group index. We ob...
متن کاملReal-space observation of ultraslow light in photonic crystal waveguides.
We show the real-space observation of fast and slow pulses propagating inside a photonic crystal waveguide by time-resolved near-field scanning optical microscopy. Local phase and group velocities of modes are measured. For a specific optical frequency we observe a localized pattern associated with a flat band in the dispersion diagram. During at least 3 ps, movement of this field is hardly dis...
متن کاملIncoherent "slow and fast light".
We show experimentally that the effects of pulse delay and advancement usually ascribed to the "slow and fast light" under conditions of the coherent population oscillations (CPO) can be universally observed with incoherent light fields on objects with the pure-intensity nonlinearity. As a light source, we used an incandescent lamp and as objects for study, a photochromic glass and a thermochro...
