Abstract
A photonic circuit including a structure of coupling to an external device, the structure including a main waveguide and at least two secondary waveguides, each secondary waveguide having a first portion substantially parallel to the main guide arranged in the vicinity of the main guide to perform an evanescent wave coupling between the main guide and the secondary guide, the first portion extending in a second portion having an end opposite to the first portion defining a coupling surface of the secondary guide, emerging at the level of an external surface of the circuit.
