Abstract
Time-resolved four-wave mixing in strongly confined and electrically pumped InGaAs quantum dots is measured at different temperatures. Without electrical injection, the dephasing time of the dot ground state transition is lifetime-limited and of several hundred picoseconds at low temperature. Under electrical injection, the sum of the contributions from empty and populated dots with a relative phase shift of π is evidenced near transparency.
