We investigate multiband optical breathers in a voltage-adjustable array of coupled waveguides in nematic liquid crystals. Symmetric breathers resulting from vector composition of modes from two bands are observed over large propagation distances and are described in terms of the Floquet–Bloch theory.

Illustration of the voltage-controlled NLC waveguide array: d, NLC thickness; Λ, array periodicity; ITO, indium tin oxide.

FB analysis of the dielectric array: (a) bandgap diagram (V=0.9 V), (b) width of gap 1 versus bias, (c) 2D FB mode profiles (density plots; darker areas correspond to higher intensity) and corresponding index distributions (contour lines) for Ky=1 in bands 0 and 1; (d) refractive index in x=0 for various voltages. The liquid crystal was 5CB with ΔRF=120, n=1.5158, K=3.2×10-12 N, n=1.6814 at 1.064 µm; the cell consisted of BK7 slides (n=1.5066) spaced by d=6 µm and with electrode period Λ=6 µm.

Beam propagation method simulation of linear and nonlinear propagation in the array: (a) A Gaussian beam is launched for V=1 V and (low) power P=0.2 mW between two adjacent channels, exciting a superposition of modes belonging to band 0; (b) as in (a) but with a narrower Gaussian beam that excites the FB modes of band 1; (c) vector symmetric breather generated by superimposing excitations (a) and (b).

Observation of breathers: (a) low- (0.2-mW) and high- (7.0-mW) power light propagation in the array for a 1-V bias. At high power a symmetric breather is visible. (b) On-axis y=0 intensity distributions corresponding to the two cases in (a).
