Abstract
An optical device includes a glass substrate provided with one or more V-shaped grooves and an optical fiber array having one or more optical fibers. The optical fiber array is fixed within the V-shaped grooves of the glass substrate using a fixing adhesive. As viewed from above, a first region Z(i.e., the region indicated by cross-hatching) and a second region Zare provided on the optical fiber array, and the fixing adhesive is applied within the first region Z. A refractive index matching resin, providing refractive index matching at least with the optical fibers, is disposed in the second region Z, wherein the second region Zmay be surrounded by the first region Z
