TL;DR: It is shown that both the spatial and the temporal behavior of a laser pulse can be stored in and recalled from theatial and spectral distribution of population in the ground state of an inhomogeneously broadened sample.

TL;DR: In this paper, a planar optical waveguide having at least one set of diffractive elements is described. And the diffracted portion of the optical signal reaches the output port as a superposition of multiple transverse modes.

TL;DR: A distributed optical structure comprises a set of diffractive elements as mentioned in this paper, and individual diffractive element transfer functions collectively yield an overall transfer function between entrance and exit ports, including diffracting regions altered to diffract, reflect, and scatter incident optical fields (altered index, surface, etc).

TL;DR: The temporal profile of photon-echo signals generated by combined gated cw and pulsed dye-laser excitation of the inhomogeneously broadened, 555.6-nm absorption line of (174)Yb vapor is studied to find that the echo profile is, after time reversal, essentially identical with that of the first excitation pulse.

TL;DR: In this paper, a planar optical waveguide has at least one set of diffractive elements and each diffractive element set routes by diffraction therefrom a portion of the optical signal propagating in the planar waveguide.
