Abstract

　本発明のジャイロは、環状の光軌道（２３）を有する共振器を備え光軌道（２３）を互いに逆方向に伝播するレーザ光Ｌ１およびＬ２を発生させるレーザ素子（２０）と、レーザ光Ｌ１およびＬ２のそれぞれを光軌道２３から引き出すための引き出し手段と、引き出されたレーザ光Ｌ１とレーザ光Ｌ２との周波数差を検出するための検出手段とを備える。共振器の光軌道（２３）の部分には、光増幅を生じるアクティブ領域（２１）と光増幅を生じないパッシブ領域（２２）とが存在する。アクティブ領域（２１）の活性層およびパッシブ領域（２２）の光ガイド層は、それぞれ、下方のクラッド層と上方のクラッド層とに挟まれている。上方のクラッド層がリッジ状であり、下方のクラッド層が平面状に広がっている。そして、アクティブ領域の活性層と、パッシブ領域の光ガイド層とが、バット－ジョイント構造で結合されている。
