| Abstract(in English) | An InGaAs/InAlAs five-layer asymmetric coupled quantum well (FACQW) theoretically shows giant refractive index change over wide wavelength region at low applied voltage and is promising for high performance optical devices based on phase shift. By introducing strain to the FACQW, valence band dispersions are modified and it improves the FACQW's electrorefractive index changes. For instance, V_π・L (product of applying voltage and modulation length) decreases by half. The proposed strained FACQW is very promising for high-performance optical modulators and switches. |
