A shadow deposited lens‐like waveguide usingrfreactively sputtered Ta2O5films onto Corning 7059 glass substrate has been fabricated. Laser beam can be successfully taper‐coupled into the waveguide from the backplate of the substrate. The focusing properties of the fabricated waveguide were observed from the photographs of multiple exposure of the laser beam ray trajectories. The effective index profiles of the deposited waveguide can be approximated by thesech(gx) function. Calculated results of the distances between focal points from thesech(gx) index profiles can fit the experimental data very well with a deviation of less than 1.8%.
