20 Quantum field theory analog effects in nonlinear photonic waveguides

Andrea Marini and Fabio Biancalana

In this chapter we discuss some recent works and developments on optical simulations and analogies with quantum mechanical/quantum field theory effects. In Sections 20.1–20.3 we focus our attention on optical waveguide arrays (WAs) that allow for the optical simulation of non-relativistic dynamics of quantum particles. They constitute a useful classical laboratory for mimicking quantum effects and can be exploited to analyze fundamental quantum mechanisms with classical tools. In addition, relativistic phenomena of quantum field theory can be optically simulated in binary waveguide arrays (BWAs), as optical propagation in the continuous ...
