The present invention consists in an optical device comprising an optical component and an optical medium with different refractive indices, said optical component being at least partly immersed in said optical medium, which device is characterized in that said optical medium contains a salt that is in the liquid state in the range of temperatures at which said optical component is used and stored, i.e. in a range of temperatures generally from −40° C. to +200° C. The optical component may in particular be a Bragg long-period grating (LPG) or a photonic crystal fiber.
An optical device, comprising an optical component and an optical medium that have different refractive indices, and wherein the optical properties of the optical component depend at least in part on the optical medium, said optical medium being external to said optical component and comprising one of (i) a salt that in the absence of a solvent is itself in the liquid state in the range of temperatures at which said optical component is used and stored or (ii) a mixture of salts that in the absence of a solvent other than one of said salts is itself in the liquid state in the range of temperatures at which said optical component is used and stored, and said optical component being at least partly immersed in said optical medium.
