Excitation of an Open Cavity via HE11 Excited Single Mode Optical Fiber for a Fabry-Perot Interferometer

Abstract

Fabry-Perot interferometer configuration consisting of a single mode optical fiber end coupled to an open cavity has been studied. The established fields inside the open cavity due to excited HE1, mode, transmission and reflection coefficients incorporating diffraction effects from the fiber end were formulated using the mode matching method. A semianalytical algorithm that accounts for the vector nature of the fields was developed and evaluated. Numerical simulations were verified against experimental measurements.
