Light induced angular steering via Floquet-Bloch band-tunnelling in one-dimensional liquid crystalline photonic lattices

A. Fratalocchi / K. Rutkowska / M. Karpierz / G. Assanto
Published Online: 2007-12-01 | DOI: https://doi.org/10.2478/s11772-007-0022-8


We investigate all-optical Zener tunnelling in electro-optically tunable arrays of identical channel waveguides in undoped nematic liquid crystals. By all-optically inducing a refractive acceleration, we demonstrate a novel technique for band-to-band tunnelling, as well as a novel approach to light controlled steering and readdressing.

Keywords: liquid crystals; photonic lattices; discrete propagation; Zener tunnelling
