Optical Nanowire Sensing<br />
Potential of Nanowire Technology for Optical Chemo- and Biosensing<br />
1. Sensitivity Enhancement of extrinsic<br />
Optical Fiber Sensors<br />
• Increasing sensitive surface applying<br />
disordered nanowires (dense grown<br />
„matted“ structures)<br />
• Resonant effects applying oriented<br />
periodic nanowire structures on fiber<br />
end-face (e.g. photonic crystals)<br />
2. Realization of Fiber Nano-sensors with tip<br />
diameters 10...100 nm<br />
• Sensibilized single nanowire as optical<br />
waveguide (evanescent field sensing)<br />
• Optical coupling to conventional fibers<br />
Si nanowires<br />
