우리는 결합 모드 이론(CMT)과 신경망(NN)을 활용하여 광 도파관 장치의 최적 설계의 계산 효율성을 향상시키기 위한 새로운 설계 접근 방식을 제안합니다. 최근에는 광학 소자의 효율적인 최적 설계를 위해 NN이 사용되기 시작했습니다. 본 논문에서는 NN을 이용하여 CMT에서 요구되는 고유모드 분석을 생략하고, 진화 알고리즘을 이용한 최적화를 효율적으로 수행할 수 있다. 우리의 접근 방식의 유용성을 검증하기 위해 파장 둔감 3dB 커플러, 1:2 전력 분배기 및 파장 역다중화기의 최적 설계 예를 제시하고 CMT와 NN(NN-CMT)을 통해 얻은 전송 특성을 비교하여 검증합니다. 유한 요소 빔 전파 방법(FE-BPM)으로 계산된 값입니다.

Abstract: We propose a new design approach to improve the computational efficiency of an optimal design of optical waveguide devices utilizing coupled mode theory (CMT) and a neural network (NN). Recently, the NN has begun to be used for efficient optimal design of optical devices. In this paper, the eigenmode analysis required in the CMT is skipped by using the NN, and optimization with an evolutionary algorithm can be efficiently carried out. To verify usefulness of our approach, optimal design examples of a wavelength insensitive 3dB coupler, a 1 : 2 power splitter, and a wavelength demultiplexer are shown and their transmission properties obtained by the CMT with the NN (NN-CMT) are verified by comparing with those calculated by a finite element beam propagation method (FE-BPM).
