抜粋

Lasing characteristics of 1.5-1.6 εm GalnAsP/InP integrated twin-guide lasers with first-order distributed Bragg reflectors (DBR-ITG lasers) are given theoretically and experimentally. At this wavelength region the fiber loss is ultimately low, but the effect of the material dispersion is serious. It is theoretically found that single longitudinal mode operation over twice the threshold current is obtainable with high quantum efficiency by optimizing the coupling properties and configurational parameters of the DBR-ITG laser. The experimental results are also demonstrated. Single longitudinal mode operation of 1.5-1.6 εm DBR-ITG lasers under high-speed direct modulation was achieved with a pulsewidth of 1.5 ns.
