Abstract

A new optical transmission network structure is proposed based on the two-dimensional magneto-optical photonic crystal and topological photonics theory, which is composed of a series of rectangular photonic crystals and air. To create coding units, the three conditions of applying a positive magnetic field, a negative magnetic field, and an air area are marked as “+1”, “-1”, and “0”, respectively. Then, three types of optical path matrix networks of 2×2, 3×3, and 4×4 are constructed. Finally, COMSOL software package is employed to simulate the transmission path of light waves. The simulation results prove that through different coding sequences, flexible and diverse control of the optical path can be achieved. The proposed control fulfils the requirements of high density optical path transmission and large-capacity information processing in the photonic integrated circuits to emerge in the future.
