Frederick Marcel Van Der Vliet, Harm Van Weerden: Optical splitter with tapered multimode interference waveguide. Gemfire Europe, Warren S Wolfeld, Haynes Beffel & Wolfeld, March 11, 2008: US07343070 (4 worldwide citation)

A 1×2 splitter design having low loss is described. The splitter has a non-adiabatic tapered waveguide (22) connected between a substantially single-mode input waveguide (20) and two output waveguides (24, 26). The non-adiabatic tapered waveguide widens in width towards the output waveguide, and mer ...
