<p>An optical coupling device wherein at least two light conductors are coupled through the intermediary of a transparent block in the shape of a half-ellipsoid on whose foci converge the end sections of the two light conductors. A light beam emerging from one conductor is reflected and transforms itself into a beam converging on the end of the second conductor. A slot permits the introduction of a liquid-crystal attenuating device connected to an alternating voltage source.</p>
