Paper Abstract

This study explores the optical field distribution of 1.55μm InGaAsP distributed feedback Laser with an air gap in the middle section. The optical field distribution was analyzed by different depth and width of an air gap. From the calculation, we could observe how the gap affect the coupling of the optical field into the other cavity. The percentage of the coupling is a crucial factor to the injection-locking operation. Both effective index model and commercial software were used to predict this coupling.
