The invention, which belongs to the technical field of the photoelectron, discloses a high-contrast-grating coupled-cavity narrow-spectral-line-width surface-emitting laser. A high-contrast grating having high reflectivity and large reflecting width is used as a reflector and is integrated to the top of a transverse-mode-based vertical-cavity surface-emitting laser; and on the basis of the high reflectivity of the high-contrast grating, emergent light of a device is fed back and photoinjection is carried out on the device, thereby obtaining a novel coupled-cavity integrated surface-emitting laser. Therefore, extension of an effective resonant cavity of the device is realized; and the spectral line width of the transverse-mode-based vertical-cavity surface-emitting laser is reduced to obtain a narrow-spectral-line-width surface-emitting laser. Because of utilization of the high-contrast-grating structure with support of the low refractive index, the integrated outer cavity preparation difficulty is reduced and the device processing process is simplified; the preparation process is a pure planar process, so that the yield and reliability of the device are improved effectively.
