(6) is the material refractive index of the active region, L is the laser cavity length, R1 and R2 are reflectivity of the DBR and external cavity mirror, Np is the photon amount in the cavity of the mode p.
The output characteristics of these devices were calculated by building up the material storage and setting optical power density, center wavelength, threshold, scan step size and calculation precision, Results and analysis The performances of device, especially the mode, the threshold and the optical-optical translation efficiency, were analyzed by dealing with different number of QWs (1, 2 and 3) in one period, QW depth, barrier width, the component and dimension of the non-absorption layer (as shown in Fig.2) [5].
