Question

A semiconductor laser is operating continuously at a certain current. Its output power changes slightly because of a transient current fluctuation. Show that the laser power will attain its original value through an oscillatory approach. Obtain the frequency and the damping time of such relaxation oscillations.

Step 1

In a semiconductor laser, the output power \( P \) is related to the carrier density \( N \) and the photon density \( S \). The laser operates at a steady state when the current is constant. A transient fluctuation in current will disturb this steady state, Show more…
