Effect of P-doping on temperature and dynamic performances of 1550nm InAs/InP Quantum Dash based lasers
10 May 2009
The effect of p-doping on both temperature and dynamic performances of 1.55mum Quantum Dashes lasers is investigated in detail. A relaxation frequency up to 13.5GHz and a damping factor as low as 0.22ns are demonstrated. The origin of this drastic improvement of the dynamic properties of Quantum Dashes lasers is discussed.
