抄録

We measured the dephasing time and radiative lifetime of excitons in InAs quantum dots fabricated using the strain compensation technique. The dephasing time at 3 K was as long as 2.86ns using transient four-wave mixing measurements at an excitation wavelength of 1.468 μm. This ultralong dephasing time was due to the significant suppression of pure dephasing.
