Abstract

The design, modeling, fabrication, and experimental measurements on optical nanobeam cavities that change resonant frequency in response to changes in the refractive index of the surrounding environment are presented. Nanobeam cavities based on Silicon-On-Insulator (SOI) that work at telecommunication wavelengths (1550 nm) provide an ideal platform for label-free sensing, due to their features of high resonance Q-factors, high sensitivity and capability for integration with silicon CMOS.
