Abstract :
Proton-exchanged LiTaO3 branching modulators are demonstrated experimentally and modeled using a normal mode coupled-mode theory. The normal modes are approximated by ordinary coupled-mode theory parameters which are experimentally obtained. Agreement between the model and the experimental results is demonstrated. Crosstalk in these linear branch devices is found to be linearly proportional to the voltage-length product, a result which leads to an analytic expression for the output power
