Quasi-Vertical Tapers for Polymer-Waveguide-Based Interboard Optical Interconnects
Abstract
A mode transformer based on the quasi-vertical taper is designed to enable high coupling efficiency for interboard-level optical interconnects involving single-mode polymer waveguides and standard single-mode fibers. A triangular region fabricated above the waveguide is adopted to adiabatically transform the mode from the fiber into the polymer waveguide. The effects of the geometrical parameters of the taper, including width, height, tip width, etc., on the coupling efficiency are numerically investigated. Based on this, a quasi-vertical taper for the polymer rib waveguide system is designed, fabricated, and characterized.
