Abstract :
Summary form only given. In this paper, we believe we report a real-index-guided 630-nm-band AlGaInP laser diode with AlInP current blocking layer for the first time. The schematic structure is shown. The device has a buried-ridge stripe structure with AlInP current blocking layer, which is transparent for the wavelength of the 630-nm-band and has a smaller refractive index than that of the AlGaInP cladding layer. The active layer is the strain-compensated multiple quantum well structure with tensile strained quantum wells and compressively strained barriers.
