Investigation of Linewidth Enhancement Factor for Two Types of Quantum Dot Laser Diode

Not Accessible

Your library or personal account may give you access

Abstract

The linewidth enhancement factor (α-factor) for two types of quantum dot (QD) laser diode (LD) was investigated. We observed that the a-factor value of the LD with a uniform QD was smaller than that of the chirped QD LD at a lasing wavelength.
