Calculation for Transmittivity of One-Dimensional Photonic Crystal: A Comprehensive Review

In this paper, a comprehensive review work is carried out on numerical analysis for transmittivity of onedimensional due to its immense applicability in photonic integrated circuit. Detailed literature survey is made for analyzing the tuning possibility of proposed bandpass filter by this structure for both normal and polarized incidence of electromagnetic wave. Structural parameters are also modified within the suitable range considering practical limit for study of the shift of passband around centered wavelength. Brief mathematical modeling is also presented, and a few works of the authors in this regard are added, which speaks for the importance of the present state of work. By highlighting the significant development in the field of photonic circuit through the implementation of photonic crystal, this paper aims to present the overall technical details carried out by eminent researchers in a short brief method.
