英文摘要	Distributed feedback lasers near 1050 nm have many applications such as high resolution imaging in medical, production inspection and 3-D sensing. In this paper, we demonstrate a purely gain coupled distributed feedback laser based on periodic electric injection. By using simple fabrication process steps, the same as those for Fabry–Perot lasers except for periodic current injection windows, we realized lasing single longitude mode in F–P structure due to surface periodic electric injection only. The device operates with a single-mode CW output of 51.9-mW power at 250 mA. The slope efficiency is 0.24 W/A, and the side-mode suppression radio is greater than 35 dB. The spectra maintain good single-mode output characteristics over a tuning range greater than 3.48 nm within only 9 �C.
