1. A method of configuration and optimisation of programmable optical devices based on meshed optical structures, a meshed optical structure comprising a highly coupled structure defined by at least three or more tunable basic units implemented with two coupled waveguides providing independent values of power and phase division; wherein the method comprises the steps of:
a. segmenting an entire mesh into tunable basic units or subsets of tunable basic units in the initial configuration,
b. determining a complete frequency response with the tunable basic units or subsets of tunable basic units in the initial configuration, wherein said complete response comprises amplitude and phase of input/output ports of a 2D waveguide mesh,
c. calculating at least one parameter of the 2D waveguide mesh from a result of the preceding step (b), and
d. modifying the initial configuration of at least one tunable basic unit or subsets of tunable basic units based on the at least one parameter calculated in the preceding step.
