论文摘要
杂化等离子光子结构将等离子响应与光子带隙结合在一起，将利用率作为光学开关和传感器的承诺。在这里，我们证明了具有两个不同外部刺激的此类结构中光学响应的主动调节，例如激光脉冲和细菌。首先，我们报告了使用飞秒激光微加工的微型（5 x 5 mm）氧化二锡氧化物（ITO）光栅的制造，并且我们显示了通过Spectrum spectrum部分中的超快光涂层通过超快光涂料中可见光的光子带隙的可能性。请注意，光谱调制的皮秒范围内所证明的时间响应具有工业相关性。此外，我们制造了一维光子晶体，该光子晶体由溶液处理的电介质bragg堆栈组成，揭示了生物活性银的顶层。我们分配了系统对Ag/细菌界面处的极化电荷的细菌反应性，从而产生了光子带隙的总体蓝移。
Hybrid plasmonic photonic structures combine the plasmonic response with the photonic band gap, holding promise for utilization as optical switches and sensors. Here, we demonstrate the active modulation of the optical response in such structures with two different external stimuli, e.g. laser pulses and bacteria. First, we report the fabrication of a miniaturized (5 x 5 mm) indium tin oxide (ITO) grating employing femtosecond laser micromachining, and we show the possibility to modulate the photonic band gap in the visible via ultrafast photoexcitation in the infrared part of the spectrum. Note that the demonstrated time response in the picosecond range of the spectral modulation have an industrial relevance. Moreover, we manufacture one-dimensional photonic crystals consisting of a solution-processed dielectric Bragg stack exposing a top-layer of bio-active silver. We assign the bacterial responsivity of the system to polarization charges at the Ag/bacterium interface, giving rise to an overall blue shift of the photonic band gap.
