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.

多层光子晶体建模的并行计算

为二维时域有限差分开发了一个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的记录过程，然后使用宽带光谱进行后续询问。此外，针对不同的薄膜厚度（从 5 到 20 μm 记录）、折射率对比度（从 4% 到 24%）、薄膜膨胀（询问膨胀范围为 110% 到 160%）模拟了光子晶体的可调响应和晶格间距（记录波长从 360 到 560 nm）。在计算机集群中实施了一种并行化方法，以减轻所需的高计算需求。通过这个模拟框架，现在可以检索有关真实光敏多层结构的相关信息。这种方法将支持用于传感器、激光器和其他功能性纳米结构光子器件的多层结构设计。
