Notes:
The high-speed modulation characteristics of ridge waveguide InGaAs/GaAs strained quantum well lasers have been investigated. The lasers have bandwidth of 12 GHz at 21 mW of output power. The differential gain coefficient, the nonlinear damping factor (κ factor) and the gain suppression coefficient (ε) are found to be 6.4 × 10−16 cm2, 0.6 ns and 6.2 × 10−17 cm3, respectively. The above differential gain coefficient and κ factor for InGaAs/GaAs strained quantum-well lasers are a factor of 2 larger than that for unstrained InGaAs/InP quantum-well lasers. The ε value for these strained and unstrained quantum-well lasers are comparable.
