Paper Abstract

AlGaInAs semiconductor lasers operating at a wavelength of 1.3 micrometers show superior performance compared to InGaAsP lasers. Ridge guide lasers are fabricated from both material systems by the same process. The characteristic temperature To for the AlGaInAs lasers (approximately 100 degree(s)K) is about twice that of the InGaAsP lasers (approximately 50 degree(s)K) resulting in substantially lower thresholds (approximately 34 mA compared to approximately 56 mA) at 85 degree(s)C. The 3-dB modulation frequency of AlGaInAs lasers is about 25% higher than that of the InGaAsP lasers.
