摘要：
A semiconductor device having a semiconductor ring laser and a base member with an electrode. The semiconductor ring laser has a circularly formed ridge optical waveguide. A concave region exists at the inside or outside of the waveguide. An electrode layer is provided over the waveguide and concave region, and the electrode and the electrode layer are electrically connected to each other through a conductive member existing in the concave region.
