Characteristics of 1.3-μm Quantum Dots Laser with a High Density and a High Uniformity QD

In this paper, we report the characteristics of a high density QD laser. In this report, we have realized high density (7.2times10

cm and high uniformity (25 meV) QD. Also, we have demonstrated a large modal gain of 54 cm

at a grand state emission of beyond 1.3 μm. It is concluded that the proposed high density and high uniformity InGaAs QD fabrication method using GC-SRL and As

source becomes a break through technique of QD laser
