Differential gain and linewidth enhancement factor in GaAs based quantum dot laser diodes
We investigated the differential gain and the linewidth enhancement factor (alpha-factor) from a 5-mum-wide stripe and 1-mm-long cavity uncoated InAs/GaAs quantum dot (QD) single mode laser diode (LD). As a result, we found that alpha-factor decreased with increasing the wavelength and was reached 0...

| description | We investigated the differential gain and the linewidth enhancement factor (alpha-factor) from a 5-mum-wide stripe and 1-mm-long cavity uncoated InAs/GaAs quantum dot (QD) single mode laser diode (LD). As a result, we found that alpha-factor decreased with increasing the wavelength and was reached 0.057 at 1286 nm. These results indicate that our QD LD has an excellent beam quality under high-power operation. |
