Abstract: PROBLEM TO BE SOLVED: To decrease the distance between an active layer and a current block layer by setting the angle of the side face of an active layer to the upper surface of a first clad layer within a specified range, touching one end of the current clock layer onto the extension above the side face thereof and inclining the current block layer by a specified angle. SOLUTION: The angle of the side face of an active layer 23 formed on a mesa-type first clad layer 22 to the upper surface thereof is set in a range of 70-90 deg.. One end of a current block layer 28 makes contact with the extension above the side face thereof, and the current block layer 28 extending from one end thereof to the underside of the active layer 23 is substantially inclined by 55 deg.. Since an embedded layer 27 existing beneath the current block layer 28 on the opposite sides of the active layer 23 becomes narrower, the region of the leak current passing through the embedded layer 27 from second clad layers 24, 29 existing above the active layer 23 is limited, thus reducing the leak current. Consequently, current-optical output characteristics can be made uniform under high temperature and high output.
