WebThe general equation for IQE is [ 65 ]: (18.5) Therefore IQE can be derived from Eq. (18.5) showing its relation with SR as follows [ 56 ]: (18.6) (18.7) From Eq. 18.6, it can be concluded that internal quantum efficiency is proportional to spectral response whereby IQE increases as SR increases. Web11.5 Operation of Semiconductor Lasers 11.5.1 Introduction: The nonlinear laser equations can easily be solved numerically on a computer. However, more insight is obtained using approximate analytical solutions in different regimes of operation. We need to solve Equations (1) and (2) above in steady state for different values of the current bias. WebTotal yield for an integrated circuitYtotalcan be expressed as follows [3].
