Abstract
Photonic sensor (CP1) comprising an interferometer (I1) having a first (BR1) and a second arm (BR2) comprising respective optical waveguides (G1, G2), characterized in that the first arm (BR1) comprises: - at least one first coupling device (DC1) between a guided propagation mode in the waveguide (G1) and a free propagation mode in an ambient medium (MA); and - an optical system (SO1) configured to direct said free propagation mode towards said or a second coupling device (DC2) between said free propagation mode in the ambient medium (MA) and a guided propagation mode in the waveguide (G1); whereby a light wave passing through said first arm carries out a part (trMA) of its path in said ambient medium.
