Programmable photonic integrated circuit and related method of operation

The present invention relates to a photonic chip carried out by the combination and interconnection of equally-oriented Programmable Photonics Processing Blocks, with all their longitudinal axes in parallel, implemented over a photonic chip that is capable of implementing one or multiple, simultaneous photonics circuits with optical feedback paths and/or linear multiport transformations, by the appropriate programming of its resources and the selection of its input and output ports. The invention also relates to a parallel field-programmable photonic array (P-FPPA) comprising of, at least one programmable circuit based on equally-oriented/parallel tunable beam-splitters with independent coupling and phase-shifting configuration and peripheral high-performance building blocks.

Photonic chip, field programmable photonic array and photonic integrated circuit

The method object of the invention enables the scalable configuration and performance optimisation to be carried out for programmable optical circuits based on meshed structures, in such a way that they can perform optical/quantum signal processing functions. The object of the invention can be applied in circuits with arbitrary degrees of complexity implemented by means of programming a waveguide mesh. The method object of the invention enables not only the analysis and evaluation of performance to be carried out, but also the subsequent programming and optimisation of programmable optical devices.

Method of configuration and optimisation of programmable photonic devices

The present invention discloses a directional photonic coupler () with independent tuning of the coupling factor and phase difference. The coupler comprises: two waveguides (), with respective propagation constants '&#x3b2;, &#x3b2;', on which phase shifters () configured to modify the propagation coefficients are located. Both phase shifters are configured such that, by independent modification (differential or unique) of the propagation coefficients, the power coupling factor (K) between an input signal (or) and the output signals (and) is tuned, and by equal and simultaneous modification of the propagation coefficients, the common phase difference of the optical output signals () is tuned. A third phase shifter () can be used to retune the phase difference at the input/output of one of the waveguides. The coupler is of particular interest in PIC circuits, coupled resonators, Mach-Zehnder interferometers and mesh structures.
