This combined photochemical-poling processing was also used to produce periodic variations in to accomplish quasi-phase-matched second harmonic generation [14]. Sekkat and co-workers [20] have conducted a much more systematic investigation of laser-assisted poling of azobenzene chromophores in a variety of polymer hosts. In particular, they demonstrated that polar order can be achieved at...

Nanometer scale domain configurations in fe bulk crystals pave the way for a new class of photonic devices. As an example, preliminary calculations show that a uv laser (A = 300 nm) based on second harmonic generation in LiTaC>3 crystal requires a periodic nanodomain superlattice with domain widths of around 700 nm. In addition, the current domain gratings in ferroelectric crystals are suitable only for quasi-phase-matched nonlinear interactions in the forward direction, where the pump and generated beams propagate in the same direction. Sub-micron ferroelectric domain gratings are the basis for a new family of devices based on backward nonlinear quasi-phase-matched optical interactions in which the generated beam travels in a reverse or another non-collinear direction to the incident beam. Non-collinear...
