Title (EN) OPTICAL DEVICE
(FR) DISPOSITIF OPTIQUE
(JA) 光デバイス
Abstract: front page image
(EN) A semiconductor laser (1) emits a laser beam, and a field absorption optical modulator (2) modulates the laser beam. The field absorption optical modulator (2) has a plurality of field absorption regions (2a, 2b, 2c) different in quenching characteristics, and thus a quenching ratio curve of the optical device can be controlled to have a shape that has a plurality of steps suited to driving conditions.
(FR) L'invention concerne un laser à semiconducteur (1) émettant un faisceau laser, et un modulateur optique à absorption de champ (2) modulant le faisceau laser. Le modulateur optique à absorption de champ (2) comporte une pluralité de régions d'absorption de champ (2a, 2b, 2c) différentes des caractéristiques d'extinction, et, par conséquent, une courbe de rapport d'extinction du dispositif optique peut être commandée pour avoir une forme qui a une pluralité d'étapes adaptées à des conditions de commande.
(JA) 半導体レーザ(1)がレーザ光を出射し、そのレーザ光を電界吸収型光変調器(2)が変調する。電界吸収型光変調器(2)は消光特性の異なる複数の電界吸収領域(2a,2b,2c)を有するため、光デバイスの消光比曲線を駆動条件に適した複数の段差を有する形状に制御することができる。
