Abstract: A method of making an optical waveguide structure having improved thermal isolation and stress reduction. The method etches both deep trenches and shallow trenches in a single step. The method includes the step of depositing a partial top clad layer over a first and second waveguide core. An etch back is then performed on the partial top clad layer to obtain a desired thickness of the partial top clad layer. A first hard mask layer is subsequently deposited over the partial top clad layer. A set of hard masks are then formed over the first and second waveguide cores by patterning and etching the first hard mask layer. A full top clad layer is then deposited over the partial top clad layer and the set hard masks to form a top clad. A second hard mask layer is then deposited over the top clad. A deep trench area and first and second shallow trench areas are then exposed by patterning and etching the second hard mask layer.

Abstract: A method of making a polarization insensitive optical waveguide structure. An optical core layer is formed on a substrate, wherein the optical core layer has a higher refractive index than the substrate. A mask is formed over the optical core layer. The unmasked areas of the optical core layer are then over-etched to define the core, wherein the over-etching removes the unmasked area of the optical core layer and a portion of the substrate disposed beneath the unmasked area, and defines the optical core. The mask is subsequently removed from the optical core. A cladding layer is then formed over the optical core and the substrate, the cladding layer having a lower refractive index than the optical core, to form a polarization insensitive optical waveguide structure. The amount of over-etching can be controlled to control an amount of substrate disposed beneath the unmasked area of the optical core layer that is removed.
