磁性フォトニック結晶の形成と超高感度バイオセンシング、超高速光スイチへの応用

等离子体光子晶体板生物传感。利用等离子体激元吸收的方法，研究了一维光子晶体中的布洛赫表面波共振现象.包括贵金属或贱金属层的这种等离子体光子晶体（PPhC）板的计算光谱中的SWR峰被证明对邻接板的介质的折射率的可忽略的变化敏感。所考虑的PPhC板的结构可能具有实际重要性，因为金属层受到覆盖电介质层的保护，免于与分析物接触，因此免于劣化。研究发现，在PPhC板的情况下，金（基于表面等离子体共振的生物传感器的关键元素）可以被其他金属取代。我的工作表明，基于PPhC的传感器可以是低成本的，可重复使用的和强大的传感器具有超过已知的光学传感器的灵敏度。

Biosensing by plasmonic photonic-crystal slab. The Bloch surface wave resonance (SWR) was visualized with the aid of plasmon absorption in a dielectric/metal/dielectric sandwich terminating a one-dimensional photonic crystal (PhC). An SWR peak in calculated spectra of such a plasmonic photonic crystal (PPhC) slab comprising a noble or base metal layer was demonstrated to be sensitive to a negligible variation of refractive index of a medium adjoining to the slab. The considered structure of PPhC slabs can be of practical importance because the metal layer is protected by a capping dielectric layer from contact with analytes and, consequently, from deterioration. It is found that, in case of PPhC slabs, gold (the key element of the surface plasmon resonance-based biosensors) can be replaced by other metals. My works show that the PPhC-based sensors can be low-cost, reusable and robust sensors having a sensitivity surpassing that of the known optical sensors.
