摘要

碳纳米管是一种与硅光子学兼容的电信带发射器，当与微腔耦合时，它们为利用量子电动力学效应提供了机会。微盘谐振器证明了与硅平台集成的可行性。利用光子晶体空气模式纳米束腔实现了高效耦合。纳米管发射的分子筛选效应允许对耦合进行光谱调谐。耦合空腔-激子系统的珀塞尔效应揭示了碳纳米管中激子近乎统一的辐射量子效率。

Optical coupling of individual air-suspended carbon nanotubes to silicon microcavities.

Carbon nanotubes are a telecom band emitter compatible with silicon photonics, and when coupled to microcavities, they present opportunities for exploiting quantum electrodynamical effects. Microdisk resonators demonstrate the feasibility of integration into the silicon platform. Efficient coupling is achieved using photonic crystal air-mode nanobeam cavities. The molecular screening effect on nanotube emission allows for spectral tuning of the coupling. The Purcell effect of the coupled cavity-exciton system reveals near-unity radiative quantum efficiencies of the excitons in carbon nanotubes.
