Theoretical analysis for different active layer structures under the same waveguide confinement is conducted to minimize the electron overflow from the active layer to the p-cladding layer for the AlGaInP laser diode. An active layer with five quantum wells and a (AlxGa1-x)InP barrier with an x composition of 0.5 has found to be the optimal structure for the AlGaInP laser diode suitable for DVD-ROM and DVD player. Experimental results have confirmed that the characteristic temperature can be as high as 110 K at far field angles of 29°/9° for this optimized AlGaInP laser diode.
