Buried glass waveguides can be fabricated using two-step ion-exchange processes. According to Fick’s law these processes can be mathematically described with the diffusion equation. We demonstrate in this work an approach based on an adjoint method to evaluate the gradient of the inverse model of one-dimensional two-step ion-exchange processes. The approach shows a consistent and efficient calculation of the gradient in comparison to the finite difference method.
