We demonstrate an electromagnetically induced transparency in a quantum dot having disk geometry under two radiation fields. It is found that electromagnetically induced transparency occurs in the system. Analytical expressions for the complex electric susceptibility, absorption, dispersion and group index are presented. The combined effects of external factors such as magnetic field, hydrostatic pressure, temperature and confinement length on the electromagnetically induced transparency are investigated. Our results may have potential applications in optical communication and quantum information processing.
