Abstract

An optical device includes: a first cladding layer (12); a core layer (13) disposed on the first cladding layer (12) and, with increase in its sectional area, extending from a first end which receives/outputs light along a direction from the first end toward a second end; a slab layer (14) disposed on the first cladding layer (12) and extending to the second end along the direction from the first end toward the second end; a rib layer (15) disposed on the slab layer (14) and, with decrease in its sectional area, extending to the second end along the direction from the first end toward the second end; and a second cladding layer disposed on the core layer (13)and the rib layer (15). The core layer (13) and both of the slab and rib layers (14, 15) are optically coupled in a part in which the sectional are of the core and rib layers (14, 15) is the maximum.
