Abstract :
Due to the use of (311)B InP substrate we grew InAs SAQD with similar qualities to the InAs/GaAs system. In addition a method using a growth interruption under P2 over pressure makes the control of the PL peak emission of the quantum dots structure easy to monitor. Thus this peak position is tuned to 1.55 μm at room temperature. This method has also been used to grow vertically stacked QDs emitting at 1.55 μm with high efficiency
