10-D-2 TEMPERATURE DEPENDENCE OF LOSSES, OF EFFICIENCY, AND OF THRESHOLD CURRENT DENSITY

We saw in Eq. (9-14) that the threshold current density is proportional to the bulk losses α. A large portion of bulk losses is due to free-carrier absorption. Since the threshold current density increases with temperature, one can readily see that the increased carrier density will cause increased losses.
