具有亚波长模式局域性的全介质反槽波导及其与输入/输出光纤的高效耦合
All-dielectric antislot waveguide with subwavelength mode confinement and its high-efficiency coupling with input/output fiber
摘要
Abstract
Due to metallic ohmic loss,plasmonic waveguides usually have larger propagation loss. Here,an all- dielectric antislot waveguide was proposed,which can realize subwavelength mode confinement and theoretically lossless propagation simultaneously. A normalized mode area of 3. 4×10-2 was achieved in the all-dielectric antis? lot waveguide. Moreover,an efficient coupling scheme between the small-size antislot waveguide and input/out? put fiber was proposed. An overall coupling efficiency of 92. 7％was attained. The misalignment tolerance for 1 dB loss penalty was about 2μm in both y and z directions.关键词
