A high-mesa waveguide is attractive as a certain portion of propagation light profiles out of the waveguide, which can be used for infrared absorption. One of the issues for a high-mesa waveguide is its propagation loss, since high propagation loss decreases the propagation light power, which restricts sensing capabilities. In this paper, we propose a silica high-mesa waveguide for infrared sensing and demonstrate its low propagation loss possibility. The implemented waveguide showed a low propagation loss of 0.02 dB/cm successfully.
