Abstract
A low threshold current of 47 Ma at 20 degrees C has been obtained in a tensile-strained index-guided AlGaInP LD emitting at 625 nm, which has an active region consisting of five 8 nm thick QWs with a lattice mismatch of -0.9%. It is shown that optimisation of the tensile-strained QW structure is very useful in improving the performance of AlGaInP LDs at wavelengths shorter than 630 nm.
