Abstract

An optical switch for coupling light between two adjacent and parallel waveguides (2,3), which waveguides are formed in a dielectric material, where a membrane (4;7;25) is provided adjacent a first (3) of said waveguides, which membrane (4;7;25) is movable between a position away from the said first waveguide (3) and a position close to or abutting the said waveguide, thereby changing the refractive index of the said first waveguide (3), c h a r a c t e r i s e d i n, that the membrane (4;7;25) is made of a dielectric material.
