摘要:

我们提出了高\emph{Q}(\emph{Q} = 36,000)聚合物光子晶体纳米梁腔的设计,制造和表征由两种聚合物制成,具有超低折射率对比度(比率=1.15)和观察到的热光双稳态在百微瓦功率水平。由于扩展的倏逝场和小的模体积,聚合物纳米梁腔是用于超灵敏生化传感的理想平台。我们证明,这些传感器的品质因数(FOM=9190)两个数量级大于表面等离子体共振传感器,并优于商业Biacore $^{\mathrm{TM}}$传感器。在低折射率对比度聚合物中的高Q腔的展示可以使用广泛的功能和柔性聚合物材料开辟多方面的应用。

英文摘要:

We present the design, fabrication and characterization of high-\emph{Q} (\emph{Q}=36,000) polymeric photonic crystal nanobeam cavities made of two polymers that have an ultra-low index contrast (ratio=1.15) and observed thermo-optical bistability at hundred microwatt power level. Due to the extended evanescent field and small mode volumes, polymeric nanobeam cavities are ideal platform for ultra-sensitive biochemical sensing. We demonstrate that these sensors have figures of merit (FOM=9190) two orders of magnitude greater than surface plasmon resonance based sensors, and outperform the commercial Biacore$^{\mathrm{TM}}$ sensors. The demonstration of high-Q cavity in low-index-contrast polymers can open up versatile applications using a broad range of functional and flexible polymeric materials.
