Design and Analysis of a 1D Ternary Photonic Crystal for Multichannel Filtering Applications
Abstrak
In this paper, we theoretically investigate the optical characteristics of a one-dimensional ternary photonic crystal (1D-TPC) structure designed for tunable multichannel filtering applications in visible region. The structure consists of a periodic arrangement of three dielectric layers—Ta2O5, SiO2, and TiO2. The optical characteristics of 1D-TPC are investigated using the Transfer Matrix Method (TMM) in the visible wavelength range (400–800 nm), which gave few transmission peaks. The number of unit cells influenced the number of transmission peaks and spectral sharpness too. Furthermore, the effect of incident angle on transmission is explored for both TE and TM polarizations. A blue shift and narrowing of transmission peaks are observed at higher angles, particularly for TE mode. These results confirm the suitability of the proposed 1D-TPC as a compact, tunable multichannel filter for photonic and optical communication systems.
