In most studies reported in literature, a flat,
constant coefficient is used to convert the amount of optical power
required at the input of an optical link into the effective power
consumption. This constant coefficient approach is very simple to
apply but not accurate, since laser efficiencies are dependent on
the optical output power in addition to the operating temperature.
In this paper the relationship between laser wall plug efficiency
and optical power output is investigated and the effect of this
variance on optical links and on-chip laser source electric power
consumption is presented
