Turn-On Delay Of Qd And Qw Laser Diodes: What Is The Difference?
15TH RUSSIAN YOUTH CONFERENCE ON PHYSICS AND ASTRONOMY (PHYSICA.SPB)(2013)
摘要
Turn-on delay of laser diodes with quantum-sized active media is investigated both theoretically and experimentally. In this research we show the striking difference in turn-on delay of quantum dot and quantum well laser diodes: With quantum-well lasers turn on delay tends to zero in the limit of high pumping, while with quantum dot lasers turn-on delay has the non-vanishing component which is independent of pumping.
