Surface emitting laser device and a light emitting device including the same

A surface emitting laser device, comprising:

• a first emitter including a first polygonal shaped aperture and a first circular shaped insulating region;
• a second emitter including a second polygonal shaped aperture and a second circular shaped insulating region and disposed adjacent to the first emitter;
• a third emitter including a third polygonal shaped aperture and a third circular shaped insulating region and disposed adjacent to the first emitter and the second emitter;
• and
• a first trench region disposed between the first emitter, the second emitter and the third emitter and forming sidewalls of the first emitter, the second emitter and the third emitter,
• wherein the first trench region is disposed inside a virtual triangle connecting a center and two corners of the first polygonal shaped aperture of the first emitter, a center and two corners of the second polygonal shaped aperture of the second emitter, and a center and two corners of the third polygonal shaped aperture of the third emitter,
• wherein the first trench region includes a first round region forming a sidewall of the insulating region of the first emitter, a second round region forming a sidewall of the insulating region of the second emitter, and a third round region forming a sidewall of the insulating region of the third emitter,
• wherein the first, second and third round regions of the first trench respectively face sides of the first, second and third polygonal shaped apertures and are disposed inside the virtual triangle,
• wherein the first trench region further includes first, second and third straight regions connecting the first, second and third round regions,
• wherein the first emitter and the second emitter are spaced apart by a first separation distance, and
• wherein a length of the first straight region is larger than the first separation distance.
