Abstract
Electroabsorption modulator based on the quantum-confined Stark effect requires large external bias voltages to induce sufficient electroabsorption effect. The external bias inevitably entails complex metal wiring, and high operating voltage causes an increase in switching energy and large heat dissipation.1'2 Therefore, it would be desirable to establish optical bistable switching without external bias for low switching energy, and layout simplification.
