Abstract :
Hollow core waveguides employing anti-resonance principle have the capability to confine the optical field in a low index medium. This characteristic can be effectively employed to build very sensitive optical sensors for biochemical and environmental applications. In this paper, a micrometer guiding structure in silicon technology is investigated, providing modal analysis and sensitivity analysis. All the results are obtained by Finite Element Method numerical simulations.
