Abstract:
An optical element has a substrate; and first to third optical waveguides formed on the substrate and each having a lower clad layer, a core layer, and an upper clad layer, the core layer having a larger refractive index than the lower clad layer and the upper clad layer. The first optical waveguide is optically connected to the second optical waveguide, and the second optical waveguide is optically connected to the third optical waveguide. The first to third optical waveguides have a mesa structure formed in a mesa shape in which at least the upper clad layer and an upper part of the core layer project above the lower clad layer. The core height of the third optical waveguide is lower than the core height of the first optical waveguide. The mesa width of the third optical waveguide is narrower than the mesa width of the first optical waveguide.

Claim (Index 1):
An optical element comprising:\n a substrate; and a first optical waveguide, a second optical waveguide, and a third optical waveguide formed on the substrate and each having a lower clad layer, a core layer, and an upper clad layer, wherein the core layer has a larger refractive index than the lower clad layer and the upper clad layer, wherein the first optical waveguide is optically connected to the second optical waveguide, and the second optical waveguide is optically connected to the third optical waveguide, wherein the first to third optical waveguides have a mesa structure formed in a mesa shape in which at least the upper clad layer and an upper part of the core layer project above the lower clad layer, wherein, when a core height is defined as a height, to a top face of the core layer, from a bottom face on both sides of the mesa structure or a position where a slope of a side face of the mesa structure is discontinuous toward the bottom face, the core height of the third optical waveguide is lower than the core height of the first optical waveguide, and wherein, when a mesa width is defined as a width of the center of the core layer, the mesa width of the third optical waveguide is narrower than the mesa width of the first optical waveguide.
