1. A method for fabricating a silica waveguide, comprising:
- defining a substantially polygonal silica pad on a silicon substrate;
forming a pillar under the silica pad, thus suspending the silica pad on the silicon substrate;
performing a laser silica reflow process on the suspended silica pad; and
, after that,cleaving at least one of the sides of the suspended silica pad to define at least one non-resonant waveguide structure with a substantially circular cross section.
