Power splitter is an important component in optical communication. Many optical devices such as optical multiplexer, switches, modulators and phased arrays utilizes power splitters as an application. In this paper, a power splitter is designed and it’s tailorability for power splitting ratio is discussed. By changing the distance between primary and one of the secondary waveguide, the ratio of power splitting is tailored.
The ratio of power splitting between primary and one of the secondary waveguide is investigated using FEM. With the variation in gap between primary and secondary waveguide, the power splitting ratio can be tailored. Result shows that power loss of ~6% is obtained during coupling phenomenon.
