Multi-channel tunable 1.55 滋m filter based on photonic crystal
A filter model with one-dimensional photonic crystal structure (AB)N was proposed. Layer A was gallium arsenide (GaAs) material and layer B was an artificial periodic structure material. B was anisotropic and made of aluminum-doped zinc oxide and zinc oxide (AZO/ZnO) alternately. Based on the theory of electromagnetic wave transmission matrix, the transmission rate of photonic crystal was derived. The numerical simulation shows that the center wavelength of the transmission is 1.55 ?滋m and corresponds to the photon pass band. The number of transmission peaks was determined by the period N of the photonic crystal. Increasing the filling factor h of the B layer from 2/3 to 11/12, the transmission peak wavelength was blue shifted and the moving range exceeds 200 nm. Increasing the thickness of the A and B layers, the peak wavelength was red shifted. When the incidence angle increases, the peak wavelength was blue shifted. The photon crystal will maintain a high transmittance within the control range of each parameter. These phenomena provide a theoretical reference for the design of multi-channel tunable high performance filter for optical communication.
