We discuss the growth and properties of an AlGaInP edge emitting diode laser. The laser structure was grown by close space low pressure MOCVD. The typical L-I characteristics of the laser with a 4 /spl mu/m current aperture are shown. The laser has a 350 /spl mu/m long cavity. The threshold current is as low as 12 mA. The external differential quantum efficiency is 37.4 %. The lasing wavelength shown is 637 nm. The threshold current decreases monotonically as the aperture size decreases to 4 /spl mu/m. When the aperture size reduced further, the threshold current increases.
