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.

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.File in questo prodotto:
