Rapidly reconfigurable optically induced photonic crystals in hot rubidium vapor
arXiv:1301.6380 · doi:10.1103/PhysRevA.87.043815
Abstract
Through periodic index modulation, we create two different types of photonic structures in a heated rubidium vapor for controlled reflection, transmission and diffraction of light. The modulation is achieved through the use of the AC Stark effect resulting from a standing-wave control field. The periodic intensity structures create translationally invariant index profiles analogous to photonic crystals in spectral regions of steep dispersion. Experimental results are consistent with modeling.
