我们提出了一个预测光子晶体无标记生物传感器性能的模型，主要基于在设备谐振的电磁近场的空间分布。为了实现最大的设备灵敏度，可以通过仔细选择材料和几何参数来形成谐振场。每个属性上的谐振模式分布的效果，因此对传感器的性能，示出。通过对器件灵敏度的计算与直接严格耦合波分析模拟结果的比较，验证了该模型的正确性。
We present a model for predicting photonic crystal label-free biosensor performance based primarily on the spatial distribution of electromagnetic near fields at device resonance. To achieve maximum device sensitivity, the resonant fields can be shaped by careful choice of material and geometrical parameters. The effect of each property on the resonant mode profile, and consequently on sensor performance, is illustrated. A comparison of device sensitivity calculated by both the proposed model and direct rigorous coupled wave analysis simulation supports the validity of our model.
