Abstract(in English) In order to realize high power semiconductor lasers with a diffraction-limited output, we propose an InGaAs angled-grating DBR laser. It consists of an angled broad-area gain stripe and surface gratings parallel to the gain stripe. The device was fabricated by a simple process without regrowth. We obtained laser oscillation and the results confirm the effectiveness of the angled-grating. A laser integrated with a grating outcoupler for collimation was also demonstrated. Single-mode lasing with a side-mode suppression ratio of 30 dB and a collimated output beam were obtained under CW operation.
