Abstract :
High power operation in 1.5 μm butt-jointed DBR lasers, made entirely by MOVPE is demonstrated. An output power of more than 30 mW and 60 mW is observed in the CW and pulsed condition, respectively. The minimum spectral linewidth achieved here is 2.1 MHz, at an output power of 12.5 mW and the wavelength chirping width under NRZ modulation is 60-70% of that of conventional DFB lasers
