英文摘要 | PURPOSE:To produce an MQW-DFB laser high in coupling factor and excellent in active layer quality and in performance characteristics by a method wherein a superlattice guide layer is first grown on a diffraction grating and the guide layer surface is ensured to be flat even in a very thin design. CONSTITUTION:On an Inp substrate 1, a diffraction grating 2 is formed by laser interference exposure, whereon a superlattice guide layer 6, consisting of ten 80Angstrom thick InP barrier layers 7 and ten 30Angstrom -thick In0.53Ga0.47As well layers 8; an MQW active layer 4, consisting of eight 100Angstrom -thick InP barrier layers 9 and eight 100Angstrom -thick In0.53Ga0.47As well layers 10; and an Inp clad layer 5, are grown in that order. The effective emission wavelength composition of the superlattice guide layer 6 is equivalent to approximately 3mum, and that of the MQW active layer 4 is equivalent to approximately 55mum. In this example, the superlattice guide layer 6 is only 1100Angstrom thick, as measured from the ridge of the approximately 500Angstrom -thick diffraction grading 2. The surface involving the growth, however, is virtually flat. |
