Abstract: PURPOSE: An electro-optic modulating device is provided to form vertical PN junctions or vertical PIN junctions in an optical waveguide, thereby increasing a change of an effective refractive index during a device operation. CONSTITUTION: A semiconductor film(30) configuring an optical waveguide(WG) is arranged on a substrate(10). The optical waveguide comprises the first slab part(SP1), the second slab part(SP2), and a lip part(RP). The lip part includes a thickness thicker than the first and second slab parts. The first and second doping areas(D1,D2) are formed on the first and second slab parts respectively. A vertical doping area(50) configuring a vertical structure is formed in the lip part.

Abstract: An optical waveguide using an epoxy resin and the fabricating methods thereof is provided to make up for the weak points of an epoxy resin by coating high polymer film having a heat-resisting property. In an optical waveguide using an epoxy resin and the fabricating methods thereof, a high polymer film(250,255) is coated on an epoxy resin for a lower clad and a upper clad respectively. The epoxy resin for the lower part and the upper clad and the high polymer film is hardened by using an UV. The lower clad is formed to remove lower PDMS master, and the upper clad is formed to remove upper PDMS. A liquid core epoxy resin is coated on an engrave pattern of the lower clad and is hardened by using UV.
