Abstract(in English) | An asymmetric triply coupled quantum well (ATCQW) was proposed and its electrorefractive effect was discussed. The ATCQW has a structure similar to a five-layer asymmetric coupled quantum well (FACQW), but is expected to exhibit larger electrorefractive index change than the FACQW does. The electrorefractive effects in GaAs/AlGaAs ATCQW for 0.9μm and InGaAs/InAlAs ATCQW for 1.55μm were analyzed and it was found that several times larger electrorefractive index change can be obtained in the ATCQWs than that in the FACQW. The GaAs/AlGaAs ATCQW was grown by molecular beam epitaxy (MBE) and was characterized by photo-absorption current measurement. Its result was consistent with the calculated. The ATCQW is a promising structure for high-speed and low voltage modulators and switches. |
