"半導體電漿奈米雷射具有突破繞射極限的能力，成功地將光壓縮到奈米尺度，展現出許多迴異於傳統微米雷射的傑出特性。本研究計畫將提出布拉格光柵式混合電漿波導結構，並以理論分析與數值模擬，有系統地探討布拉格光柵式混合電漿波導結構的光學特性，進而設計新型半導體電漿奈米雷射。由於混合電漿波導模態耦合了波導模態與表面電漿模態，將展現出高侷限化強近場及低損耗的光學特性；布拉格光柵則利用週期結構的效應，使結構兼具高反射及低損耗的優點。新型半導體電漿奈米結構的研究將做為高性能及低損耗半導體電漿奈米雷射元件設計時之依據。" "Semiconductor plasmonic lasers at submicron and nanometer scales exhibit many characteristics distinct from those of their conventional counterparts at micron scale. The differences originate from their small sizes and presence of metal plasma surrounding the cavity. In this project, novel hybrid plasmonic waveguide nanolasers with Bragg grating reflectors will be proposed and analyzed. We will establish a detailed theoretical model for full 3D structure simulations by taking into account both geometry and metal dispersion. Moreover, we will develop a systematic procedure for analyzing this class of hybrid plasmonic waveguide nanolasers with Bragg grating reflectors, and evaluate the optimization of performance such as light output power, threshold reduction, and output beam shaping."
