Abstract

Sharply bent optical fiber can be used as sensory systems. At first sight, application of curved optical fiber is refractometer but after immobilizing metal layer on stripped core of optical fiber its usage can be much more sophisticated. On the metal layer it is possible to excite surface plasmon polariton. In our case we use Drudes model of free electron and Monte Carlo method to calculate probability and real possibility of excitation of surface plasmon polariton on metal layer applied on the core of U-bent optical fiber. The calculated results allow for direct assessment of appropriate positions of metal layer on semi-toroid optical fiber in dependence on system parameters.
