Abstract
To form an optical element ( ), in particular an interferometric sensor, an optical fiber ( ) is placed tangent to a cylindrical supporting element ( ); a straight portion ( ) of the optical fiber and the supporting element are surface fused; and a cavity ( ) is formed in the optical fiber ( ), the cavity being defined by facing surfaces ( ) of the straight portion ( ) substantially perpendicular to the axis of the straight portion ( ). The optical fiber ( ) and supporting element ( ) may be subjected to traction during surface fusion, to form a small cross-section portion close to the cavity, and which, when light is conducted by the optical element, provides for reducing the amount of light dispersed in the cavity.
