摘要

摘要开发了一个二维时域有限差分模拟框架来模拟多层光子晶体结构。该框架包括通过相干光源在光敏材料中记录过程,然后用宽带光谱进行后续询问。此外,对于不同的膜厚度(从5到20记录),模拟了光子晶体的可调谐响应  μm)、折射率对比度(从4%到24%)、膜膨胀(以110%到160%的膨胀进行询问)和晶格间距(以360到560nm的波长记录)。在计算机集群中实现了一种并行化方法,以缓解所需的高计算需求。通过这个模拟框架,现在可以检索到关于真实光敏多层结构的相关信息。该方法将支持传感器、激光器和其他功能性纳米结构光子器件中使用的多层结构的设计。

Parallel computing for modeling multilayer photonic crystals
Abstract. A simulation framework is developed for the two-dimensional finite-difference time-domain to model multilayer photonic crystal structures. The framework includes the recording process in a photosensitive material through a coherent light source and then a subsequent interrogation with a broadband spectrum. Moreover, the tunable response of the photonic crystal is simulated for different film thicknesses (recorded from 5 to 20  μm), refractive indices contrast (ranging from 4% to 24%), film expansions (interrogated with expansions ranging 110% to 160%), and lattice spacings (recorded with wavelengths from 360 to 560 nm). A parallelization method was implemented in a computer cluster to alleviate the required high computational demand. Through this simulation framework, it is now possible to retrieve relevant information about realistic photosensitive multilayer structures. This method will support the design of multilayer structures utilized in sensors, lasers, and other functional nanostructured photonic devices.
