摘要 | PURPOSE:To obtain a stable longitudinal single mode selectivity and to vary an oscillation wavelength in a range of 10nm by applying a magnetic field from a specific direction to a semiconductor laser device. CONSTITUTION:An InGaAsP active layer 2 doped with 0.5wt.% of erbium with an organic metal epitaxially grown layer, a P-type InGaAsP antimeltback layer, a P-type InP clad layer 4, a P-type InGaAsP can layer 5 are sequentially grown in a multilayer from top of an N-type InP substrate Then, a P-type side electrode 6 and an N-type side electrode 7 are formed by an electron beam depositing method, cleaved 300mum of resonator to obtain a desired laser structure. A coil 8 is provided above and below semiconductor lasers 1 - 7, and a magnetic field is applied in a direction of an arrow. Thus, an oscillation wavelength can be varied over a range of 10nm, and it can be oscillated in a longitudinal single mode over this wavelength varying range. |
其他摘要 | 目的:通过将来自特定方向的磁场施加到半导体激光器件,获得稳定的纵向单模选择性并改变10nm范围内的振荡波长。组成:掺杂有0.5wt。%铒的InGaAsP有源层2,有机金属外延生长层,P型InGaAsP反熔层,P型InP包层4,P型InGaAsP罐层5依次然后,通过电子束沉积方法形成P型侧电极6和N型侧电极7,切割300mum的谐振器以获得所需的激光器,从而形成多层的N型InP衬底1的顶部。结构体。线圈8设置在半导体激光器1-7的上方和下方,并且沿箭头方向施加磁场。因此,振荡波长可以在10nm的范围内变化,并且它可以在该波长变化范围内以纵向单模振荡。 |
