要約
(EN)
An optical transmitter has: a ring waveguide; electrodes, which are formed in the vicinity of the ring waveguide, and which have signals applied thereto; a first waveguide, which is optically coupled to the ring waveguide; a second waveguide, which is optically coupled to the ring waveguide without being optically coupled to the first waveguide directly; and a light source, which supplies continuous light to the first waveguide.
(FR)
L'émetteur optique faisant l'objet de la présente invention comprend : un guide d'ondes annulaire ; des électrodes situées à proximité du guide d'ondes annulaire et sur lesquelles sont appliqués des signaux ; un premier guide d'ondes couplé optiquement à ce guide d'ondes annulaire ; un second guide d'ondes couplé optiquement audit guide d'ondes annulaire sans être directement couplé optiquement au premier guide d'ondes ; ainsi qu'une source de lumière fournissant une lumière continue au premier guide d'ondes.
(JA)
 光送信器は、リング導波路と、リング導波路の近傍に形成された、信号が与えられる電極と、リング導波路と光学的に結合する第1の導波路と、第1の導波路と光学的に直接結合することなくリング導波路と光学的に結合する第2の導波路と、第1の導波路に連続光を供給する光源と、を有する。
