We describe the spectral and high-speed modulation properties of 1.3-μm semi-insulating blocked planar buried-heterostructure distributed feedback lasers. We demonstrate the first single-frequency lasers with the capability for large-signal modulation at a bit rate as high as 16 Gb/s. The lasers exhibit a relatively small increase in spectral linewidth due to chirp even under high-speed modulation conditions.
