H. Wenzel et al., Effect of band gap renormalization on threshold current and efficiency of a distributed Bragg reflector laser, APPL PHYS L, 76(19), 2000, pp. 2653-2655
The threshold current and the external efficiency of a three-section distri
buted Bragg reflector laser are investigated as a function of a forward ele
ctrical bias applied to the passive sections. Within a well-determined rang
e, the threshold current increases and the external efficiency decreases wi
th increasing bias. This effect is attributed to band gap renormalization.
