Abstract: A hybrid vertical cavity laser includes an optical circuit substrate including a grating having refractive index units having a lower refractive index and a higher refractive index with respect to each other that are alternately arranged in a first direction, and a waveguide guiding light in the first direction, a mesa structure on the optical circuit substrate, the mesa structure including a first-type semiconductor layer including an exposed portion, an active layer, a second-type semiconductor layer, and an upper reflective layer sequentially stacked in a second direction perpendicular to the first direction, a first electrode on the exposed portion, and a second electrode on the upper reflective layer. An overlapped length between the waveguide and a mesa aperture forming an opening through which light produced from the active layer enters the grating is D, a pitch of the grating is p, and 0
