Intellectual Merit: The intellectual merit of this study consists of developing active Nanophotonic Superpolariton Junctions (NSJ) by inserting light-guiding optical fibers into tapered glass-membrane nanopores to form nano-scale transistors of light. Actively adjusting the insertion distance and the permittivity of a 'soft' dieletric material between the fiber and nanopore is expected to enhance field intensity and detection sensitivity at the NSJ tip 35-fold. Active adjustments improve transfer of energy from incoming light to oscillating, surface electrons (called 'polaritons') at the tip while the unique NSJ geometry reduces 'polariton' losses. Supporting this study develops an active alternative to existing passive light-to-polariton transistors that are difficult to prepare and produce 10-fold increases in field intensity.Broader Impacts: This study will educate three graduate students, including two underrepresented females, in active nanostructures, photonics and sensing within a highly collaborative environment of 70 faculty who fabricate and analyze nano-scale devices like microarrays and lab-on-chips. The social impact of this study includes having undergraduates demonstrate NSJs in hands-on instructional modules prepared for class demonstrations, summer workshops and lab experiences for community college and high school students across the state. These demonstrations are part of a 5-year NSF (STEP)-sponsored collaboration co-initiated by the PI that plans to increase participation, improve retention, and ultimately double enrollment of underrepresented minorities in STEM courses. The economic impact of this study arises from NSJ applications that include photonic circuits, high-density magneto-optic data storage, highly-sensitive spectroscopic nano/bio/chemical sensors and high-resolution near-field optical microscopy.

智能价值：这项研究的智能价值包括通过将导光光纤插入锥形玻璃膜纳米孔来开发有源纳米光子超极化结(NSJ)，以形成纳米级的光晶体管。积极调整纤维和纳米孔之间“软”介电材料的插入距离和介电常数，有望将NSJ尖端的场强和探测灵敏度提高35倍。主动调节改善了能量从入射光到尖端振荡表面电子(称为“极化子”)的传递，同时独特的NSJ几何结构减少了“极化子”损失。支持这项研究开发了一种主动替代现有的被动光到偏振晶体管，这些晶体管很难制备，场强增加了10倍。广泛的影响：这项研究将在一个由70名教师组成的高度协作的环境中教育三名研究生，包括两名未被充分代表的女性，在一个由70名教师组成的高度协作的环境中制造和分析纳米级设备，如微阵列和芯片实验室。这项研究的社会影响包括让本科生在为全州社区大学和高中生的课堂演示、暑期研讨会和实验室体验准备的动手教学模块中演示NSJ。这些演示是由美国国家科学基金会(STEP)共同发起的为期5年的NSF(STEP)合作的一部分，该合作计划增加参与率，改善保留率，并最终将STEM课程中代表不足的少数族裔的入学人数增加一倍。这项研究的经济影响来自NSJ的应用，包括光子电路、高密度磁光数据存储、高灵敏度光谱纳米/生物/化学传感器和高分辨率近场光学显微镜。
