Paper Abstract

We investigate optical spatial solitons in a one-dimensional periodic stack whose unit cell is composed of two materials possessing quadratic nonlinearities and subjected to an array of microheaters. The periodic temperature gradient induces a variation in the refractive index due to the thermooptic effect. In contrast to ordinary photonic crystals, in such thermo-laminated system one may easily change parameters such as period and modulation depth of the induced index modulation. Furthermore, one can easily translate the modulation in time and introduce defects. We have found that is possible to steer solitons, change its shape, split it in two or more lower power solitons and move them independently.
