Fiber to resonator coupling multicriteria optimization with COMSOL multiphysics

In this paper, we discuss the principle of coupling an optical signal to an optical resonator. We give the broad outlines of the principle and the experimental parameters then we look at how to optimize this coupling using finite element simulations on COMSOL software. Simulation of the coupling is based on straight and ring waveguides placed very close to each other so the waveguide can be transmitted from one to other.
