Abstract
A diffusion-based material model is implemented and linked to the Crank–Nicholson beam propagation method to carry out numerical investigations on self-written bent waveguide couplers on a polymer basis. Such couplers are established in a photopolymer mixture when two opposing Gaussian laser beams with an offset or gap along their propagation axes traverse through a medium and the beams, eventually, get self-trapped. In this work, numerical investigations of the processes involved with respect to the temporal dynamics of refractive index modulation and the corresponding intensity profiles are presented. We also show that compensation for misalign-ments or gaps is possible as the coupling length of the structure increases. Furthermore, we report and analyze the curing time and curvature of the bent couplers, which are regulated by control of model parameters such as propagation distance between opposing beams, component concentrations, and the value of the rate constant during the simulation process.
