Abstract :
Long-wavelength GaInAs(P)/InP quantum well laser diodes (QW LDs) are described with respect to the epitaxial growth technique used, their QW structure, and the cavity design. QW LDs with graded-index separate-confinement heterostructure (GRIN-SCH), grown by metalorganic chemical vapor deposition (MOCVD), exhibit low threshold current density (410 A/cm/sup 2/), low threshold current (6 mA), high characteristic temperature (153 K), and high output power (100 mW). Preliminary aging tests have been carried out at 50 degrees C, 5 mW and at 70 degrees C, 5 mW. N appreciable change in driving current was seen after 7000 h, indicating the high reliability of these devices.<>
