Modelagem tensorial aplicada à acopladores ópticos triple-core planar e triangular

Optical devices have been widely used in telecommunication, information transmission and sensing systems. Among these devices, we have the optical coupler, responsible for dividing the light beams and switching the optical signals. The present work aims to propose a new modeling of optical signals for triple-core couplers, by introducing a transfer tensor, which can be seen as a generalization of the transfer matrix commonly defined for dual-core couplers. Numerical simulations are provided to analyze the device performance and to illustrate the effectiveness of the proposed model.
