| titleOfInvention | Structure and frabicating method of distibuted feedback laser |
| abstract | A structure of distibuted feedback laser (DFB) is disclosed, wherein, a phase-shift grating structure and a gratingless area are included in the grating layer of the DFB, in addition, both side-surfaces of the DFB are coated with the anti-reflection coating in order to improve the SMSR as well as to obtain a good slope efficiency (SE). The grating layer is divided by the phase-shift grating structure along a horizontal direction into a first grating area and a second grating area, wherein a laser-out surface of the DFB is adjacent to the second grating area. The phase-shift grating structure provides a phase-shift distance, such that a shift of phase exists between the micro-grating structures located within the first grating area and the other micro-grating structures located within the second grating area. The gratingless area is located within the second grating area and is without any micro-grating structure, and moreover, the gratingless area will not change the phase of the micro-grating structures located within the second grating area. |
