| Abstract(in English) | We report on the saturable absorption properties of high-density InAs quantum dots which is developed for 1.5μm communication devices. Ultrafast (^～1ps) and slow (>100ps) relaxation times are obtained by pump and probe measurements with 200fs pumping pulse, and the modulation depth of more than 1% caused by saturable absorption is estimated by measurements of pumping intensity dependence of absorption saturation. We examine possibility of the application of the high-density InAs quantum dots to mode-locker for short optical pulse generation while comparing with other quantum well saturable absorbers. |
