▲ [10a-W331-8] Investigation of impact of InGaAsP quantum well on the modulation efficiency of III-V/Si hybrid MOS optical modulator
キーワード:optical modulator, semiconductor quantum well
A numerical analysis of the impact of InGaAsP quantum well(QW) on the modulation efficiency of III-V/Si hybrid MOS optical modulator has been done. Thanks to a lighter electron effective mass in narrower bandgap InGaAsP, and the employment of quantum well structure, the modulation efficiency could be improved by more than 20%.
