摘要 | PURPOSE:To obtain a distribution feedback type laser with oscillating wave length at designed value subject to favorable yield by a method wherein, after GaInAsP active layer and a guide layer is preliminarily grown, a cyclic structure as a double hetero structure is formed on GaInAsP layer. CONSTITUTION:An N type InP layer 12, no additive layer 13, P type GaInAsP guide layer 14 are liquid epitaxially grown on (001) surface of N type Inp substrate 1 A resist film is interference exposed by means of He-Cd layer and developed to form a mask further etching a layer 14 to form a cyclic structure 15 (period 4,700Angstrom ) with stripes in parallel with the direction of (-110). Next N type InP layer 16 and P type GaInAsP layer 17 are laminated and a current narrowing structure is introduced to complete a distribution feedback type laser. In such a constitution, the cyclic structure provided on GaInAsP layer 14 with less P component resistant to dissociation of P i.e. thermal deteroration will not be destroyed even if the layer 16 is grown at 590-520 deg.C favorably controlling oscillating wave length to obtain the oscillating wave length at designed value. |
其他摘要 | 目的:通过一种方法,在GaInAsP有源层和引导层预先生长之后,在GaInAsP层上形成作为双异质结构的环状结构,以获得具有设计值的振荡波长的分布反馈型激光器,其具有良好的成品率。 。组成:N型InP层12,没有添加剂层13,P型GaInAsP引导层14液体外延生长在N型Inp基板11的(001)表面上。抗蚀剂膜通过He-Cd层干涉曝光和开发以形成掩模,进一步蚀刻层14以形成具有与(-110)方向平行的条纹的环状结构15(周期4,700埃)。接下来层叠N型InP层16和P型GaInAsP层17,并引入电流窄化结构以完成分布反馈型激光器。在这种结构中,即使层16在590-520℃生长,有利地控制振荡波长以获得振荡波长,也不会破坏GaInAsP层14上提供的具有较少P组分的抗循环结构的环状结构,即热阻止。振荡波长在设计值。 |
