Demonstration of a cylindrically symmetric second-order nonlinear fiber with self-assembled organic surface layers

Opt Express. 2011 May 23;19(11):10326-35. doi: 10.1364/OE.19.010326.

Abstract

We report the fabrication and characterization of a cylindrically symmetric fiber structure that possesses significant and thermodynamically stable second-order nonlinearity. Such fiber structure is produced through nanoscale self-assembly of nonlinear molecules on a silica fiber taper and possesses full rotational symmetry. Despite its highly symmetric configuration, we observed significant second harmonic generation (SHG) and obtained good agreement between experimental results and theoretical predictions.
