Derivation of the refractive index profile equation of K-Na ion-exchange waveguide by a rapid thermal method

급열법에 의한 K-Na 이온교환 도파로의 굴절율 분포식산출

A detailed theoretical and experimental study of k-na exchange in soda lime silicate glasses by RTP is presented. Concentration profiles i.e. index profiles are given by complementary error function added Gaussian function. The estimated diffusion coefficient is 1.54${\mu}{\textrm}{m}$2/min.
