Abstract :
A theoretical model for the design of three-section distributed Bragg reflector (DBR) lasers using the transfer matrix method is presented. The oscillation parameters, the tuning behavior, and the linewidth are derived. The effect of a discontinuity of the waveguide at the active-passive interface is accounted for by using scattering matrix parameters, easily combined with the transfer matrix method. The influence of such an interface is studied and the importance of optical losses at this point is discussed
