Off-the-shelf laser diodes with narrow-line emission at visible wavelengths by integration of distributed feedback (DFB) surface grating (Conference Presentation)

Paper Abstract

The development of laser diodes at visible wavelengths have revolutionized the technological era. Nowadays, specialized applications such as atomic cooling, sensing, and optical communication require not just a conventional laser but a narrow-line or single-wavelength laser source. Herein, we report the demonstration of narrow-line emission directly from commercial InGaN-based laser diodes by monolithic integration of distributed-feedback (DFB) surface grating. Our results obtained at continuous wave (CW) current injection and room temperature reveal spectral lasing linewidth in the picometer range on wavelengths between 460 nm and 520 nm.
