High-Speed Performance of 1.55 μm Buried Hetero-Structure Lasers with 20 InGaAsP/InGaAlAs Quantum-Wells


1550 nm re-grown FP lasers having 20 InGaAsP/InGaAlAs strain-balanced QWs exhibit low threshold current density, high T0 (78.0°C) and high resonance frequency (24 GHz) indicating that a large number of shallow barrier QWs are attractive for un-cooled high-speed direct-modulation applications.
