Description
本発明に係る第1の実施形態について説明する。本実施形態に係る波長可変レーザ装置のブロック構成図を図1に示す。図1において、波長可変レーザ装置10は、光導波路20、光増幅手段30、波長制御手段40、位相制御手段50、反射手段60および放熱手段70を備える。
第2の実施形態について説明する。本実施形態に係る波長可変レーザ装置の平面図を図2に、図2のA−A’線における断面図を図3に示す。図2において、波長可変レーザ装置1000は、基板100、半導体光増幅器(SOA:Semiconductor Optical Amplifier)200、外部共振器300および放熱構造800によって構成される。
第3の実施形態について説明する。本実施形態に係る波長可変レーザ装置の平面図を図6に示す。第2の実施形態で説明した図2の波長可変レーザ装置1000においては、放熱構造800を基板100の上面のヒータ610の下方に配置したが、本実施形態に係る波長可変レーザ装置1000Cにおいては、放熱構造800Cを、基板100の上面の波長制御部500の下方に配置する。すなわち、本実施形態においては、ヒータ610の下方は空間のままとし、熱干渉を抑制したい波長制御部500の下方に放熱構造800Cを配置する。
第4の実施形態について説明する。本実施形態に係る波長可変レーザ装置の平面図を図7に、図7のB−B’線における断面図を図8に示す。図7の波長可変レーザ装置1000Dは、ヒータ610Bによって温度制御される第2の光導波路420Bの長さを長くすることで、第2の光導波路420Bの温度を大きく変化させ、第2の光導波路420Bを通過する光の位相変化を大きくする。
