Summary :

A multilayered optical coupler is described which is used to couple a laser beam into a thin film waveguide. This device adopts an evanescent-field coupling technique based on a tapered-gap prism coupler. The multilayered coupler configuration without moving parts results in a mechanically stable coupling function. Experimentally, coupler insertion loss of 3 dB, including coupling imperfection loss, Fresnel reflection loss, and waveguide loss in the coupling region, was achieved in coupling an He-Ne laser beam with 0.633 µm wavelength into a 0.33 µm thick SiO₂-Ta₂O₅ waveguide.
