摘要
A visible light laser diode includes an etching stopping layer having a lower etching rate in an etching solution than a cladding layer, having a larger band gap energy in bulk than the band gap energy of the active layer, including a layer that stops etching, and having a band gap energy exceeding an energy corresponding to the oscillation wavelength of the visible light laser diode. Therefore, the cladding layer can be selectively etched with satisfactory controllability to a predetermined shape. After the etching process, even with a laminated etching stopping layer partly remaining in the cladding layer, the etching stopping layer does not absorb light emitted from the active layer.
