Optical Power Transfer in Directional Couplers by Ahmed Ali is a document available to read on EtoBox.
This paper presents an analytical approach to analyzing optical power transfer in linear step index directional couplers using the Helmholtz equation and characteristic matrix method, addressing inaccuracies found in traditional coupled-mode theory for small gaps. The study focuses on the relationship between various waveguide parameters such as gap width, guide depth, and coupling length, demonstrating their non-linear interactions. The simulation employs a Ti:LiNbO3 system to validate the findings and enh
