A multilevel retro-coupling device for an electromagnetic radiation, including at least one first level (n1) and one second level (n2) at least partially superposed, the first level including a first waveguide intended to guide a propagation of the light radiation in a first direction (s1) and the second level comprising a second waveguide intended to guide the propagation of the light radiation in a second direction (s2) opposite the first direction, the device including: a coupling portion, wherein the first and second waveguides are coupled by moving them closer to one another, such that the electromagnetic radiation is propagated from the first level (n1) to the second level (n2), and at least one reflector at an end of the coupling portion, configured to reflect the electromagnetic radiation.
A multilevel retro-coupling device for a light radiation, comprising at least one first level (n1) extending along a first plane (xy1) and a second level (n2) extending along a second plane (xy2) parallel to the first plane (xy1), said first and second levels being at least partially superposed in a direction (z) normal to the first and second planes (xy1, xy2), the first level comprising at least one first waveguide configured to guide a propagation of the light radiation in a first direction (s1) and the second level comprising at least one second waveguide configured to guide the propagation of the light radiation in a second direction (s2) opposite the first direction, the device comprising:
