In this study, a one-dimensional periodic ring multi-connected optical waveguide network is designed to solve the problem of obtaining ultra-wide photonic band gaps. The analysis of the network's spatial structures and numerical relations reveals a common characteristic that the photonic band gap width is independent of the number of nodes in a unit cell of the optical waveguide network. By comparing it with existing optical waveguide network schemes, the potential practicability of the network is explored, showing advantages of lower complexity for the spatial topology, better scalability, and better structural invariance.
In this study, we design a one-dimensional periodic ring multi-connected optical waveguide network to solve the problem of obtaining ultra-wide photonic band gaps that are too complex for the photonic band gap width to be tuned. Analysing the spatial structures and numerical relations of our network reveals a common characteristic that the photonic band gap width is independent of the number of nodes in a unit cell of the optical waveguide network. Based on this character, we explore the potential practicability of our network by comparing it with existing optical waveguide network schemes. Our network has the advantages of lower complexity for the spatial topology, better scalability of the spatial topology, and better structural invariance.
