ABSTRACT:
A buried dual taper waveguide has a flat surface after taper processing thus facilitating further processing with more complex photonic integrated circuits. This allows for light coupling between a large core size fiber and a small waveguide photonic integrated circuit. The taper structure disclosed enables monolithic integration of silicon photonic components and passive alignment for low-cost packaging.
