Abstract(in English) | To reduce the hole pile-up and increase an optical power handling capacity in 40 Gbit/s semiconductor optical modulator, we fabricated three devices whose active layers consist of multi-quantum-well (MQW) having barrier bandgap wavelengths λ_b of 1.18, 1.3, and 1.4 μm. Escape times of holes from active layer were accurately measured to confirm the effect of longer λ_b on the promotion of carrier escape from well layers. The escape time becomes smaller with increasing λ_b and reaches a limit determined by the drift time in the active layer. Optical input power dependence of EO response was also measured accurately to quantify the optical power handling capacity. Devices with λ_b=1.3 and 1.4 μm have larger capabilities by 2-3 dB than the device with λ_b=1.18 μm. |
