Integrated optical circuit and methods for its manufacturing and reconfiguring

A method for manufacturing and reconfiguring an integrated optical circuit, comprising the following steps:

• (a) providing a substrate, wherein the substrate is equipped with at least one reception for at least one external connector, wherein the reception is coupled to at least one connector waveguide;
• (b) placing a layer of a material onto the substrate;
• (c) creating within the layer of the material placed onto the substrate at least one set of nano-optic components, wherein the nano-optic component is one of a nanophotonic waveguide or a nanophotonic component, wherein the nanophotonic component is nano-optically coupled to at least one nanophotonic waveguide, wherein at least one of the nanophotonic waveguides is selectively coupleable to at least one of the connector waveguides;
• and
• (d) providing at least one photonic wire , wherein the photonic wire connects at least one of the connector waveguides to at least one of the nanophotonic waveguides;
• wherein, after step (d), at least one of the photonic wires comprised in the integrated optical circuit is removed, and wherein at least one further photonic wire is provided in the integrated optical circuit.
