We describe the structure and performance of tunable four-quantum-well InGaAs/InGaAsP distributed Bragg reflector lasers. We observe total tuning range as large as 94 Ã…, differential efficiency of 32%/front facet, thresholds of 17 mA, low-chirp high-speed digital operation, and linewidths as low as 5.75 MHz at only 2 mW output.
