Polymeric multimode waveguide based electro-optic modulator with a vertically configured dumping planar waveguide

An electro-optic modulator based on a polymeric multimode waveguide coupler was developed. A guiding multimode waveguide with a vertically configured dumping planar waveguide was employed in the design to increase the device packing density. A modulation depth of 91% at 1330 nm was experimentally achieved. This device shows that the multimode optical waveguide with the vertically configured dumping planar waveguide is promising in electro-optic modulator designs. This modulator can be used in multimode optical interconnection systems such as data communications and fiber sensor networks.
