double-layer waveguideとは 意味・読み方・使い方

To facilitate the designing of an electric device formed on a semiconductor layer of a front surface in forming a thick portion, e.g. an optical waveguide on the semiconductor layer sandwiched by a double-layer insulator.例文帳に追加

２層の絶縁体層に挟まれた半導体層に肉厚部、例えば光導波路を形成する場合に、表面側の半導体層に形成される電気デバイスの設計を容易とする。 - 特許庁

The loaded layer 3 is formed by a double-layer structure which is constituted of two layers which are provided with a refractive index being larger than that of the optical waveguide 2, which consist of niobium oxide and which have different refractive index.例文帳に追加

装荷層３を、光導波路２の屈折率よりも大きい屈折率を有し、かつ、ニオブ酸化物からなり屈折率の異なる２つの層によって構成された二層構造とする。 - 特許庁

On at least one of the top and reverse surfaces of a waveguide core 4 provided on a lower clad layer 3, a stress adjusting film 6 or 7 which has a small coefficient of thermal expansion is provided and thus the strain of the waveguide core 4 is suppressed to prevent double refraction from being caused, thereby obtaining the optical waveguide having no polarization dependency.例文帳に追加

下部クラッド層３の上に設けられた導波路コア４の上面もしくは下面の少なくとも一方に熱膨張係数の低い応力調整膜６、７を設け、導波路コア４の歪みを抑制することにより、複屈折の発現を防止し、偏光依存性のない光導波路を得る。 - 特許庁

The coherent light source is equipped with an active region 4 provided with an active layer 8 emitting light rays by a current injection, a double electrode semiconductor laser 2 with a phase adjusting region 5 equipped with a layer that is continuously joined to the active layer and varied in refractive index by a current injection, and an optical waveguide device 3 where a DBR (distributed Bragg reflector) region 7 is formed.例文帳に追加

電流注入により発光する活性層８を有する活性領域４、および活性層に連続して配置され電流注入により屈折率変化を生じる層を有する位相調整領域５が設けられた二電極半導体レーザ２と、ＤＢＲ（分布ブラッグ反射器）領域７が形成された光導波路デバイス３とを備えたコヒーレント光源。 - 特許庁
