Abstract: We demonstrate that voltage-controlled negative index can be obtained inself-organized InAs quantum dot systems. As the bias voltage changes, therefractive index can be adjusted and controlled continuously from -7 to 7.Simultaneously, the absorption of light in the system will be very small. Thesingle-negative index materials and the double-negative index materials can beachieved in different bias voltages.
