Optimizing Optical Performance in DFB Cavities through Advanced Parameter Variations

EasyChair Preprint 15401

Abstract

This paper presents an in-depth study of the Distributed Feedback (DFB) cavity model using the transfer matrix method to optimize optical performance in photonic applications. Various parameters, including effective refractive index, grating lengths, and cavity lengths, are analyzed to observe their impact on the reflectivity and transmissivity of the DFB cavity. Numerical simulations are conducted using the transfer matrix method to model the interaction of light with the periodic variations within the cavity. The results show optimal configurations that can enhance wavelength selectivity in DFB cavities. This study contributes to the design of efficient photonic devices, specifically in lasers and optical filters. The simulations provide significant insights for guiding the development of high-performance DFB lasers.
