Cs:KTiOAsO4 optical ion-exchanged waveguides

Optical waveguide layers Cs:KTiOAsO4 are realized by ion-exchange method. The doping level as 21 mol. percent Cs is achieved. The function of refractive indices increase profiles is identified as erfc-type. The absence of dispersion of indices increase over visible region is detected. The coefficients between indices increase and Cs concentration are obtained.
