“…The design of a novel plasmonic slot supporting complex plasmonic modes for gas sensing 4 will also be presented. The design optimization of metal coated silica nanowire for bio sensing 5 and doped ZnO coated gold nanowire 6 for gas sensing and a resonating straight slots 7 for biosensing will also be presented. All these devices and waveguides were simulated by and their sensing responses were investigated with our in-house full-vectorial finite element method.…”

Although optical sensors incorporating grating inscribed and etched fibres are now sufficiently mature and well established in the market, however, designs based on more exotic nanowires and photonic crystal fibres 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. In compact Integrated Optic format, dielectric slots, plasmonic slots, Mach-Zehnder interferometer, and ring resonators are also emerging as novel photonic sensors. However, high index contrast also makes the modes in such sensing structures fully hybrid in nature and in such a case, full-vectorial rigorous numerical approaches will be necessary for their design optimization. Some selected results for silicon based compact photonic sensors will be presented illustrating the value and potential of the computationally efficient finite element method in such designs.
