Abstract
Precise evaluation of the facet reflection is highly desirable in design and simulation of optoelectronic devices such as super-luminescent light emitting diodes (SLEDs) and semiconductor optical amplifiers (SOAs) where ultra low facet reflection must be achieved. In this paper, the three-dimensional (3D) finite-difference time-domain (FDTD) method has been implemented on a parallel computing algorithm for the calculation of facet reflection in optical waveguides. The result has shown that even a subtle difference in the waveguide ridge shape and facet tilting scheme has significant impact on modal reflectivity.
