Nonlinear discrete optics in femtosecond laser-written photonic lattices

In recent years, photonic lattices fabricated by the femtosecond laser direct writing technique in fused silica have emerged as the tool of choice for the experimental investigation of light propagation in discrete optical systems with Kerr nonlinearity. In this article, we review the recent results of our research conducted in this field and present our latest findings on the reflection of transversely propagating light at kinks in planar photonic lattices with detuned pivotal site.
