In this study, we investigated the optical properties of periodic and quasiperiodic multilayer structures and its application for light filtering in optical communication.
Multi-layer 1-dimensional photonic crystals consist of several layers of various refractive indices, often arranged in a periodic or quasi-periodic sequence.
Such multilayer photonic structures have recently shown excellent optical properties and can be utilized in multi-channel optical filters and high reflectance mirrors.
We consider a regular periodic and four quasi-periodic multi-layer configurations for applications in optical dense wavelength division multiplexing (DWDM) filtering and other multiplexing/de-multiplexing applications
We used FDTD method for simulation and compared the result characteristics with the ITU-T standard.
