Well-barrier (W-B) hole burning in quantum well lasers is argued to be a consequence of the carrier build up in the barrier during the capture and release of carriers by the quantum well. The rate in this process are characterized by a capture time ($tau$-c$/) and by the in/out ratio ($eta@) defined as the ratio of the capture and release times for carriers into and out of the well region. In this paper a circuit model to represent W-B hole burning that is responsible for a large change in the threshold current density have been developed from the ratio equations. The model is simulated using the circuit simulation program SPICE for various values of $eta and compared for a QW with and without W-B barrier hole burning.
