Slow light
‘‘New Problems’’ resumes this month with the first of a series of problems from Kirk McDonald of Princeton University. ‘‘New Problems’’ continues to solicit interesting and novel worked problems for use in undergraduate physics courses beyond the introductory level. We seek problems that convey the excitement and interest of current developments in physics and that are useful for teaching cours...
متن کاملSlow light beam splitter.
We demonstrate a slow light beam splitter using rapid coherence transport in a wall-coated atomic vapor cell. We show that particles undergoing random and undirected classical motion can mediate coherent interactions between two or more optical modes. Coherence, written into atoms via electromagnetically induced transparency using an input optical signal at one transverse position, spreads out ...
متن کاملSlow-light spatial solitons.
We numerically and experimentally report the observation of slow-light spatial solitons in a Kerr medium owing to light amplification by stimulated Raman scattering. This was achieved in a CS2 nonlinear planar waveguide that possesses both a strong self-focusing nonlinearity to generate the spatial Raman soliton and a Raman susceptibility sharp enough to induce the slow-light process simultaneo...

Consider a classical model of matter in which spectral lines are associated with oscillators. In particular, consider a gas with two closely spaced spectral lines, ω1,2 = ω0 ±∆/2, where ∆ ≪ ω0. Each line has the same damping constant (and spectral width) γ, where γ ≪ ∆. Classically, one might expect these oscillators to correspond to the “V” configuration of atomic levels sketched in Fig. 1a), ...
