ABSTRACT:
An optical device includes a substrate, a core provided on the substrate, a first clad and a second clad formed around the core. The optical device further includes a light absorber layer, provided on the substrate, which absorbs light leaked from the core. The light absorber layer is formed of, for instance, the same material as that constituting the core.
