A surface-emitting device with an embedded circular grating coupler is developed. A uniform grating coupler with 0.4-/spl mu/m pitch and 0.15-/spl mu/m depth is fabricated by electron beam lithography and reactive ion etching. The grating is well embedded by an overgrown layer. It is shown that the lasing oscillation is successfully achieved up to the measured temperature of 196 K where the absorption loss at the grating coupler is well suppressed, and a stable single-longitudinal-mode oscillation is obtained.
