Abstract

Conventional self-electro-optic effect device (SEED)1 is based on the red-shift of the effective bandgap due to the quantum-confined Stark effect (QCSE). On the other hand, blue-shifting SEED schemes were proposed2 and implemented based on QCSE in strained (111) structures3 and Wannier-Stark localization.4 The blue-shifting scheme has in principle lower residual absorption and requires lower operational voltage than the conventional SEED and is also less sensitive to temperature and laser wavelength than is the conventional SEED.
