Nonlinear Effects Analysis in DBR Lasers: Applications to DBR-SOA and New Double Bragg DBR

IEEE Journal of Selected Topics in Quantum Electronics, 2007
This paper presents a theoretical and experimental study of nonlinear effects in distributed Bragg reflector (DBR)-type tunable lasers, which are responsible for asymmetric spectral or power characteristics, and for hysteresis phenomena. We propose an optimized DBR semiconductor optical amplifier design that suppresses these effects, making the control
