介绍了一套新型光学传感器的设计和优化，显示了采用严格的全矢量数值方法的价值。尽管基于光纤的光学传感器在市场上已经很成熟，但基于纳米线和光子晶体光纤的设计正变得越来越重要，并且通过访问更大的倏逝场显示出更高的灵敏度。同样，新颖的平面设计概念，如基于硅槽导轨的设计，显示出更大的前景，允许开发良好的CMOS制造技术，用于潜在的低成本传感器元件。文中列举了数值高效有限元方法在系统设计中的价值和潜力。
The design and optimization of a suite of novel optical sensors is presented, showing the value of using rigorous full-vectorial numerical approaches. Although fibre based optical sensors are well established in the market, designs based on more exotic nanowires and photonic crystalfibres are becoming increasingly important and showing much improved sensitivity by accessing a larger evanescent field. Similarly, novel planar design concepts, such as the silicon slot guide-based design is showing even greater promise, allowing the exploitation of well developed CMOS fabrication technologies for potentially low-cost sensor elements. Someselected results illustrating the value and potential of the numerically efficientfinite element method in systems design are presented.
