Abstract
An optical waveguide includes a first core and a second core disposed adjacent to each other at spaced intervals and a dummy core positioned between the first core and the second core. The first core and the second core transmit light in a transmission direction perpendicular to an adjacent direction. The dummy core includes a facing surface facing the first core and an opposing surface positioned at the opposite side to the first core with respect to the facing surface, and the opposing surface has an inclined surface inclining so as to go away from the first core toward the downstream side in the transmission direction.
