中文摘要:
      为解决传统等离子光学传感器的局限性,提出了一种基于黑磷(BP)的多共振非等离子体的光学传感器,该传感器采用单层黑磷和简单的介质结构,通过磁共振增强红外波吸收。由于黑磷的各向异性,该传感器可以在不同晶体方向上实现不同的灵敏度和品质因数(FOM)。通过优化传感结构,在8 μm波长附近的不同黑磷晶体方向上均得到了2个极窄的共振峰、极低的半高宽,提高了传感器的灵敏度,吸收率最高达到了99.6%,灵敏度最高可达180 nm/RIU,FOM可以达到 261 nm/RIU。并利用耦合模理论对仿真结果进行了验证,揭示了其物理机理,证实了该传感结构在未来的光学传感领域有巨大的潜力。
英文摘要:
      In view of the limitation of traditional plasma optical sensors, and being capable of enhancement of absorbing infrared waves by magnetic resonance, a multi resonant non plasma optical sensor based on black phosphorus (BP) is proposed. A BP monolayer and a simple dielectric structure are adopted by the sensor, Due to the anisotropy of BP, the sensor can achieve different sensitivities and figure of merits (FOMs) in different crystal directions. Through optimizing the sensor structure, two resonant peaks which are very narrow are obtained in different directions of BP crystals around 8 μm wavelength, and the sensitivity of the sensor is improved by the relatively low full width at half maximum. The highest absorption rate reaches up to 99.6%, while the highest sensitivity reaches up to 180 nm/RIU and FOM reaches up to 261 nm/RIU.The simulation results are verified by the coupled mode theory, and the physical mechanism is revealed. The sensor structure has great potentials for the future optical sensing application.
