| 英文摘要 | PURPOSE:To enlarge the variable tuning width of an outgoing wavelength by providing a phase control region having a broad forbidden band width between a plurality of distribution feedback regions so as to control the amount of phase shift. CONSTITUTION:This device is composed of: a plurality of distribution feedback regions 100 and 101; a phase control region 200 which is disposed between a plurality of distribution feedback regions and combines with the distribution feedback regions optically and, further, makes it possible to control the amount of phase shift from the outside; a saturable absorption region 102 where the distribution feedback regions and the phase control region combine each other optically. In addition, both end faces of the element have low reflection structures. Moreover, a certain relation of Eg1 |
