This study elucidates the dynamic characteristics of an optical fiber coupler via the differential quadrature simulations. A novel modeling scheme is suitable for developing an optical fiber coupler application. Exactly how the locations of bonding points, string tension, and spring stiffness of the rubber pad affect the dynamic behavior of the optical fiber coupler is investigated.
