Abstract: | Threshold current and differential quantum efficiency of broad contact lasers with asymmetric facet reflectivity are discussed
with the purpose to reveal factors essential for optimisation of the wall-plug efficiency of such lasers. Lasers with low
front facet reflectivity and short cavity often exhibit behaviour difficult to explain with a classical theory. More rigorous
calculation performed in this work show that differential quantum efficiency is indeed less affected by a change of the front
facet reflectivity or cavity length than predicted by such theory. These findings greatly simplify criteria for optimisation
of the wall-plug efficiency of broad contact lasers with coated facets. |
