| titleOfInvention | DFB laser structure containing DFB laser mirror coating |
| abstract | The utility model belongs to the technical field of the radium-shine of semiconductor, especially, relate to a radium-shine structure of DFB who contains radium-shine mirror surface coating film of DFB. The utility model discloses the radium-shine structure of DFB contains base plate, buffer layer, active layer, grating layer, goes up waveguide layer, goes up the cladding layer, upper and lower two sides electrode to and the HR high reflection coating film area that is located the AR low reflection coating film area of preceding light-emitting terminal surface and is located back light-emitting terminal surface, this AR/HR coating film area all uses aluminium nitride to plate as coating material and makes and form. The utility model uses AlN as the mirror coating film, on one hand, the heat dispersion of the device can be effectively improved, and the operation current and the output power of the laser are greatly improved, so that the device can meet the use requirements of higher speed and higher power; secondly, the working time of laser can be effectively prolonged, the service life of the laser is prolonged, and premature failure of the laser is avoided; in addition, the problems of small protrusion or film peeling and the like caused by expansion with heat and contraction with cold in the film coating process can be avoided. |
