Question

Electrical Engineering

(e) In the steady state and above threshold, why will the gainand carrier density inside a semiconductor laser be clamped(limited)to the threshold condition? How about photon densityinside the cavity? If the driving current is time varying form, aregain and carrier density still kept in constant values? How aboutin AC driving conditions?
