Abstract: In this paper we investigated the influence of mismatch between the fiber and waveguide modes on the fiber-waveguide coupling loss. We measured the wavegu-ide mode width and depth versus the metal Ti strip width.By determining the appropriate waveguide parameters,it is found that the coupling loss between the fiber and waveguide is very low.

Key words: single fiber, coupling loss, waveguide
