Application of simulated annealing to design and realisation of two-dimension fibre-type optical phased array

The necessity of an optimisation procedure in optical phased array (OPA) design has been demonstrated. Simulated annealing was used to perform the numerical simulation. The analysis studies the scheme of a two-dimensional fibre-type OPA with piezoelectric ceramics (PZT) phase shifters. Moreover, an experimental system has been set up to confirm the integrity of the design.
