Silicon-on-sapphire waveguides design for mid-IR evanescent field absorption gas sensors

We investigate three types of SOS waveguides suitable for evanescent field absorption based gas sensing in mid-IR. Rib and slot waveguide shows greater quasi-TE evanescent field than strip waveguide. 1.33ppm resolution is achievable.
