Abstract :
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 simpler and more reliable, while maintaining the same performances as a DBR (16 nm tuning, 40 dB side mode suppression ratio, 20 mW coupled output power). Aiming to reach C-band tuning range with only one Bragg current control and reduced nonlinear effects, a new double Bragg DBR laser is proposed.
