Esteban Martínez, Óscar ; Navarrete Fernández, María Cruz ; González Cano, Agustín ; Bernabeu Martínez, Eusebio | Elsevier Sci. Ltd. | 2000-03In this work we present an application of a simple quasi-geometrical model to analyze the behavior of compound waveguide structures used as fiber-optic sensors. This theoretical model is based on the adjustment of the parameters of the structure[...]![]()

Theoretical method for the study of plasmon generation in hybrid multilayer-optical fiber structures
A theoretical method is presented for the determination of the behavior of devices based on the deposition of multilayer structures on polished optical fibers. Plasmon generation in metallic layers is modeled. The method is based on the Rayleigh[...]![]()
