Abstract

The authors describe the structure and properties of multisection tunable dynamic-single-mode multiple-quantum-well (MQW) distributed-Bragg-reflector (DBR) lasers operating at 1.5 μm. These lasers display a low threshold, excellent differential quantum efficiency, and a large tuning range, with both low chirp under high-speed direct modulation and narrow linewidth under CW operation. Curves are presented showing: (1) the CW light-current characteristic for both a 507 μm total length two-section device and a 1250 μm total length three-section device at 23°C with no current to the Bragg or phase sections; (2) wavelength vs. Bragg tuning current for two different active length two-section devices; and (3) linewidth vs. inverse optical power for the two-section device. The results show that, at a fixed Bragg current, the SIPBH geometry makes the two-section tunable MQW DBR an excellent dynamic-single-longitudinal-mode source. Low chirp also results from the smaller α factor obtained in these devices.
