Paper Abstract

Deep Zn diffused stripe GaAs/GaAlAs double heterostructure lasers grown by metalorganic chemical vapor deposition for fiber optic transmitter applications are reported. Stripe widths of 2, 4, and 8 pm are examined in terms of laser threshold currents and far-field radiation patterns. For lasers with a 4 pm stripe, threshold currents as low as 40 mA, a characteristic temperature as large as 170°C, and external differential quantum efficiencies as high as 80-90% are obtained. Single mode operation of these lasers is observed. Preliminary results on the device uniformity and high-speed modulation characteristics are includded.
