Abstract

In this paper a novel modal converter based on an asymmetric dual-core photonic crystal fiber is proposed and numerically analyzed by using the full-vector finite element method. This converter allows mode conversion between the LP01 and LP11 modes, and the LP01 and LP21 modes. These modes are obtained at 1.55 µm. In addition, it was found that the operating wavelength of this device has a great dependence on the different geometric parameters of the structure, such as the diameter of the holes and the pitch as well. Finally, a compact device that can be used in the O + S + C + L + U bands with efficiency greater than 80% and a total length of 2 mm was obtained. This is a very interesting alternative to fabricate new all-fiber optic devices that could be implemented in mode division multiplexing systems.
