Broadly-Tunable Dynamic-Single-Mode Multiple-Quantum-Well Semi-Insulating-Blocked Distributed-Bragg-Reflector Lasers at 1.5microns.
18 March 1988
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 94angstroms, 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.
