New Model of Incident Gaussian Beam for Analyzing Optical Communication Devices using Thin Film Filter

초록

Ray-optic approach is very useful for analyzing characteristics of passive micro-optical devices [1]. Recently, we have proposed the efficient method of modeling an incident beam for the approach [2]. In this paper, the improved ray-model of Gaussian beam propagation is proposed and applied to characterization of micro-optic devices with thin-film optical filters. While previous methods used a lot of rays for simulating the Gaussian beam accurately, the proposed method could simulate Gaussian beam and provide more accurate coupling efficiency with even using fewer rays (shown in fig.1).
