We report the fabrication of a fiberized micrometer-size ridge waveguide using a sheet-stacking method. The fabrication conditions for maintaining the ridge geometry with micrometer dimensions were investigated and discussed. A loss of 3.9 dB/m was measured at 1.55 mu m in the fiber ridge waveguide, showing no extra loss above the bulk loss of the glass. A high birefringence of 9.5 x 10(-3) was measured in the waveguide at 1.55 mu m which is close to the reported highest birefringence (1.1 x 10(-2)) in optical fibers. Fusion splicing was successfully employed to splice the fabricated waveguide to a conventional silica fiber with reasonable loss.
