Abstract

The design and analysis of a novel photonic crystal electro-optic modulator are presented in this paper. The device incorporates an electro-optic (EO) polymer slot waveguide into the center of a silicon photonic crystal waveguide. In this device, strong optical confinement in the EO polymer core and small group velocity from the photonic crystal structure provide a surprise enhancement of the EO effect.

실리콘과 전광 고분자 물질을 기반으로 한 새로운 광 결정 광변조기를 제안하고, 설계 및 검증을 수행하였다. 이는 실리콘 물질로 된 광 결정 도파로의 중심에 전광 고분자 물질로 된 슬롯 형태의 도파로를 삽입한 구조로 구성된다. 좁은 폭의 전광 고분자 슬롯도파로를 진행하는 광 신호는 주변의 광 결정 구조에 의해 매우 낮은 군속도를 갖게 될 뿐만 아니라, 전광 고분자 내로의 강한 광학적 구속력을 갖게 되어 광-물질 간의 활발한 상호작용과 매우 높은 전기-광학적 효과를 얻을 수 있다.
