Electromagnetically Induced Coherent Backscattering [PDF]

open access: yesPhysical Review Letters, 2006
We demonstrate a strong coherent backward wave oscillation using forward propagating fields only. This is achieved by applying laser fields to an ultra-dispersive medium with proper chosen detunings to excite a molecular vibrational coherence that corresponds to a backward propagating wave.

Dynamic Coherent Backscattering Mirror [PDF]

open access: yesCLEO: 2013, 2013
The phase of multiply scattered light has recently attracted considerable interest. Coherent backscattering is a striking phenomenon of multiple scattered light in which the coherence of light survives multiple scattering in a random medium and is observable in the direction space as an enhancement of the intensity of backscattered light within a cone ...
