The present invention relates to a light emitting device capable of reducing saturation of a gain, and promoting high output. In the light emitting device (100) according to the present invention, an optical waveguide (160) comprises: a first region (161) including a center position C; a second region (162) including a first light emitting surface (170); and a third region (163) including a second light emitting surface (172). A second cladding layer includes a plurality of non-contact areas (18). The plurality of non-contact areas (18) intersect the optical waveguide (160). A ratio of an area in which the plurality of non-contact areas (18) overlap the first area (161) to an area of the first area (161), is greater than a ratio of an area in which the plurality of non-contact areas (18) overlap the second area (162) to an area of the second region (162). Also, the ratio of the area in which the plurality of non-contact areas (18) overlap the first area (161) to the area of the first region (161), is greater than a ratio of an area in which the plurality of non-contact areas (18) overlap the third area (163) to an area of the third region (163). |
