ABSTRACT:
A fully light-controllable integrated optical switch applicable in a slab geometry configuration includes a waveguide and an ad-medium in contact with the waveguide. The the ad-medium comprises a photochromic protein as a material of non-linear optical property, wherein switching of a light propagating in the waveguide is effected by a change of an optical property of the ad-medium caused by a light-induced transition of the photochromic protein from one defined molecular state to another.
