Abstract

A novel ultracompact polarization beam-splitter (PBS) combining two plasmonic multimode interference couplers (P-MMICs) and DFB guiding structure is implemented. The $2{\times}1$ and $1{\times}2$ P-MMICs are designed to collect the polarized powers of TE and TM modes reflected by or transmitted through an internal DFB structure. The simulation results show that the designed DFB-assisted PBS is very short (about $75{\mu}m$), and has a low insertion loss, a high extinction ratio, and a broad bandwidth of 20 nm.

2개의 플라즈마 다중모드 간섭 결합기 (P-MMIC)와 DFB 전송구조를 결합하여 하나의 새로운 초소형 광 편향기를 구현하였다. $2{\times}1$과 $1{\times}2$ P-MMIC를 연결하는 내부 DFB 구조로부터 반사되거나 투과되는 TE, TM 모드들의 편향된 전력들을 P-MMIC를 통하여 출력되도록 설계하였다. 수치해석 결과 설계된 DFB 구조형 플라즈마 다중모드 간섭 결합기의 크기는 약 $75{\mu}m$로 매우 작았으며, 낮은 삽입손실과 높은 분리비율을 보였다. 더욱이, DFB 전송구조의 대역폭은 약 20 nm로 광대역 특성을 나타내었다.
