Abstract

The invention provides an optical waveguide device and method of manufacturing the same. No light path block article exists between the light-emitting element and optical waveguide, wherein, light-emitting elements are provided on the substrate; an under-cladding layer provided on a portion of the upper surface of the substrate except for the light emitting element provision region is provided; and a core covering the light emitting element and the under-cladding layer on the substrate and serving as a path of light emitted from the light emitting element, is formed. The core fixes up the light-emitting element and makes the light generated from self-luminescence elements to directly irradiate in.

Description

[0001] technology area [0002] The present invention relates to an optical waveguide device widely used in optical communication, optical information processing, and other general optics and a manufacturing method thereof. Background technique [0003] Generally, in an optical waveguide device, light emitted from a light-emitting element is propagated using an optical waveguide (see, for example, US5914709). Figure 5 The optical waveguide device is schematically shown. Figure 5 In the optical waveguide device, an optical waveguide composed of a lower cladding layer 20 , a core layer 30 , and an upper cladding layer 40 is formed on a substrate 10 . Then, the light emitting element 50 is spaced apart from the one end side of the optical waveguide, and the light emitting element 50 is fixed to the substrate 10 via the adhesive A. The light L emitted from the light emitting element 50 enters from one end surface of the core layer 30 of the optical waveguide, passes through the ...
