| 英文摘要 | PURPOSE:To obtain a large variable tuning width of selected wavelength by interposing a distributed feedback area which has a phase shift structure between plural active areas, coupling the active areas with the distributed feedback area optically, and forming the end surfaces of the active areas in nonreflection structure. CONSTITUTION:The distributed feedback area which has the phase shift structure is interposed between the plural active areas, which are coupled optically with the distributed feedback area; and the end surfaces of the active areas are formed in nonreflection structure. Further, when a relation Eg1 |
