Abstract
Description
短波長になると、モードホップを引き起こす共振器長のズレが小さくなることに加え、屈折率分散が増加することから、モードホップフリー同調は飛躍的に困難になる。実際、市販の波長可変レーザのモードホップフリー同調領域は1μm帯で30nm程度、可視光域ではモードホップフリー同調は10nm以下に制限されている。
どの波長域においても高出力で広帯域に同調可能な波長可変レーザが求められている。しかし、高出力動作や広い利得帯域を得るためにはチップ長の長いレーザダイオードを用いる必要があるが、長いチップ長は屈折率の波長分散による光路長の変化が大きくなるため、モードホップフリー同調域は狭くなってしまうという問題があった。
