Abstract

Using modal transmission-line theory (MTLT), it explores rigorously the polarization characteristics of plasmonic optical polarizer. To verify the validity of the approach proposed in this paper, a novel polarization condition, which is called mode suppression ratio, is defined. The numerical results reveal that the polarization length of plasmonic optical polarizer is $10{\mu}m$ dramatically shorter than that of conventional dielectric optical polarizer. Furthermore, the insertion loss of plasmonic polarizer consisting of metal Ag is small enough to be neglected below -1dB.

모드 전송선로 이론을 이용하여 플라즈마 광 편파기의 편파특성을 정확하게 분석하였다. 제안한 해석법의 타당성 및 정확성을 분석하기 위하여 새로운 편파조건인 모드 억압비율(mode suppression ratio)을 정의하였다. 수치해석 결과, 플라즈마 광 편파기는 유전체로 구성된 전형적인 광 편파기에 비하여 편파거리가 현저하게 짧은 $10{\mu}m$로 나타났다. 또한, 플라즈마 광 편파기를 구성하는 금속 성분인 Ag에 기인한 삽입손실은 -1dB 이하로 무시할 정도로 작았다.
