Classification: CPC G | IPC G

Claim 13:
14. A method of forming a photonic assembly, comprising the following steps:
a step of providing a photonic device comprising a first block including at least one output guide and at least one input guide cooperating with, respectively, at least one first output and at least one first input arranged on a first face of the first block;
a step of providing a photonic element including at least one second output and at least one second input, arranged on a second face of the photonic element;
a step comprising arranging an optical isolator interposed on a first light propagation path between the at least one first output and the at least one second input, and imposing a first mode size on a radiation propagating along the first light propagation path;
a step comprising arranging an adjustment device interposed on a second light propagation path between the at least one first input and the at least one second output, the adjustment device being configured to impose on a radiation propagating according to the second light propagation path a second mode size equal to the first mode size, wherein the adjustment device comprises a plate of a thickness Te, the plate comprising a material of optical index Ne, the thickness Te and the optical index Ne being such that the second mode size is equal to the first mode size; and
an optical coupling step comprising optically coupling the at least one second output and the at least one second input with, respectively, the at least one first input and the at least one first output.
