Abstract
Description
外部共振部からの光出力を取り出すための光分岐部として、光分岐部34は反射部36と光アンプ部20の間に位置する。出力は分割されて、一方は、光変調器へ導波される。他方は、共振器を形成するのに必要なフィードバックを提供する反射部へ導波される。1×2型マルチモード干渉導波路以外に2×2型マルチモード干渉導波路、Y分岐導波路または方向性結合器は、光分岐部として使用されうる。
位相制御部18は、反射部36と光分岐部34の間に位置し、電流を注入して、実効的な反射率を変化させることによって、発振波長を精密に調整するために使用される。
位相制御部18への注入電流によって、実効的な反射率は変化し、発振波長は正確に調整されうる。
反射部36は光集積回路チップ内で提供される場合には、エッチングで空間が形成されて、金(AU)が供給されて金属がコーティングされ、またはチップ内でエッチングされて形成されるエアギャップ又は回折格子により、光ビームの反射を可能にしている。例えば、光分岐部34は、1×2型マルチモード干渉導波路として構成される。
