First Observation of Ultraslow Group Velocity of Light in a Solid

Not Accessible

Your library or personal account may give you access


Electromagnetically induced transparency (EIT) has been the subject of many experimental and theoretical studies over recent years.1 Most recently, substantial experimental and theoretical work in this area has been focused on the use of EIT to give ultraslow group velocities for light in both ultracold atomic gas2 and hot atomic vapors.3-5 Much of this interest is based on the fact that slowing the group velocity of a laser pulse down to the speed of sound in the same material can produce strong coupling between acoustic waves and electromagnetic field.6 It has been suggested that a giant nonlinearity obtained by this method might be utilized for efficient multi-wave mixing and quantum nondemolition measurements.7 Slow light might also allow a very efficient nonlinear interaction between laser pulses of extremely low (down to a single photon) energies.8 Here, we report the first direct observation of an ultraslow group velocity of light down to 45 m/s in a solid, well below the speed of sound in the medium.
