| Abstract: | We theoretically investigate cavity-linewidth narrowing by means of voltage-controlled induced transparency in asymmetric double quantum dot system. The impact of voltage on frequency pulling and cavity linewidth narrowing is discussed. The linewidth and position of the cavity transmission can be engineered by the bias voltage. The scheme may be useful in designing novel optoelectronic devices. |
