We experimentally demonstrate an anti-parity-time (anti-PT)-symmetric photonic lattice in
thermal cesium atoms driven by two standing-wave laser fields. Such a lattice possesses …

Orbital angular momentum (OAM) light is nowadays an intriguing resource in classical and

A photonic crystal (PC) having the structure (AB) NA is investigated. A and B are
superconductor and dielectric layers, respectively. P-polarized (TM) wave is assumed to be …

We demonstrate a scheme to control the spatially dependent hyper-Raman scattering based
on electromagnetically induced transparency in a cold atomic system. By adjusting the …

We have experimentally generated a vortex six-wave mixing (SWM) signal via a photonic
band gap structure in a hot atomic ensemble. The output SWM carrying orbital angular …
