Description
最初に本願発明の実施形態の内容を列記して説明する。
図1(a)は、第1実施形態に係る半導体レーザの平面図である。図1(b)は、図1(a)のIb−Ib線矢視断面図である。図1(a)及び図1(b)に示されるように、半導体装置である半導体レーザ1は、例えばDFB(Distributed Feedback)型の半導体レーザである。半導体レーザ1は、例えば半導体基板11上に、光吸収領域2、SG−DBR(Sampled Grating Distributed Reflector)領域3、SG−DFB(Sampled Grating Distributed Feedback)領域4、及びSOA(Semiconductor Optical Amplifier)領域5を有する。半導体基板11は、例えばInPを含むn型の半導体基板である。
以下では、第2実施形態に係る半導体レーザの制御方法について説明する。第2実施形態の説明において第1実施形態と重複する記載は省略し、第1実施形態と異なる部分を記載する。つまり、技術的に可能な範囲において、第2実施形態に第1実施形態の記載を適宜用いてもよい。
