Abstract
Provided is a micro optical circuit including a first micro optical waveguide and a second micro optical waveguide with a boundary face therebetween, in which the height of the first and second micro optical waveguides is different from each other, and the side faces of the first micro optical waveguide are connected to the side faces of the second micro optical waveguide at first and second connection points in a plan view. An intersection between the boundary face and the center line equidistant from the two side faces of the second micro optical waveguide is present in a region between a first straight line and a second straight line in a plan view, the first straight line passing through the first and second connection points, the second straight line crossing the second micro optical waveguide so as not to cross the first micro optical waveguide.
