Abstract Single-longitudinal-mode gain-coupled distributed feedback (DFB) lasers based on high-order gain-coupled surface gratings emitting at 770 nm window are implemented. The periodic surface metal p-contact with insulated grating grooves realizes a gain coupled mechanism. Our devices provided a single longitudinal mode with the maximum CW output power up to 116.8 mW@400 mA with facet coated (HR>99%, AR
