Optical waveguides and method of fabrication thereof

   
   

Optical waveguides of the type which include a light-transmitting core and a cladding layer on said core. The optical waveguide can be planar or cylindrical such as an optical fiber. The optical waveguide is provided with an additional coating of highly biaxial or uniaxial crystalline material with different refraction indices in different directions.

Guide di onde ottiche del tipo che includono un nucleo luce-trasmettente e uno strato del rivestimento sul nucleo detto. La guida di onde ottica può essere planare o cilindrica quale una fibra ottica. La guida di onde ottica è fornita di un rivestimento supplementare del materiale cristallino altamente biassiale o monoassiale con differenti indici di rifrazione nei sensi differenti.
