Abstract EN
This paper presents a way to mitigate the influence of temperature effects on the equilibrium point (Q-point) of vertical cavity surface emitting lasers (VCSELs) by investigating the effect of laser injection current (Iinj) and dc-bias level (Ibias) numerically using MATHCAD software.
Results show that, by changing temperature 50 oC (i.
e.
from 10 to 60) with Iinj = 3Ith and Ibias = 0, the photons density (P(t)) has decreased from 1.636 × 1016 cm-3 to 0.733 × 1016 cm-3, the carrier density (N(t)) has increased from 2.367 × 1018 cm-3 to 2.669 × 1018 cm-3 and the laser output power (Pout) has decreased from the 2.366 mW to the 1.025 mW.
In contrast, by increasing the Iinj from 3Ith to 5Ith and the Ibias from 0 to 1.5Ith, the rate of the decreasing in the P(t) and in the Pout have reduced more than 25% .
