Abstract (en)
[origin: WO2010000824A1] The invention relates to a waveguiding structure, including a carrier substrate and a waveguide including at least one guide layer having an index of n1. Said layer includes a birefringence B area that includes recesses provided in the body of the guide layer and filled with a fluid or material having an index of n2. They are organized along at least two parallel rows, each row located in a plane perpendicular to the surface of the guide layer and parallel to the propagation direction of the optical wave in the guide layer; each row extending across a distance greater than or equal to the wavelength of the optical wave; the width of the recesses being = 1/10th of the wavelength of the optical wave; each recess within a single row being spaced apart from an adjacent recess at a distance of = 1/10th of the wavelength of the optical wave; the biorefringence B value following the Formula (I), ff being the fill factor of the material having a refractive index of n1; nH,TE (nB,TE) and nH,TM (nB,TM) being, respectively, the actual refractive indices of the mode TE and the mode TM of the guide layer having a higher (or lower) refractive index.
