    Abstract: PROBLEM TO BE SOLVED: To solve a problem of fluctuation in modulation characteristics depending on wavelength and intensity of light input to an optical modulator, thereby achieving operational stability of the modulator.
    SOLUTION: In an optical modulator waveguide used for the optical modulator of one embodiment, a part of a second n-type semiconductor clad layer touching a semi-insulating clad layer serving as a semiconductor clad layer (barrier layer), or a part of the second n-type semiconductor layer and the semi-insulating clad layer (semiconductor clad layer) is formed as a p-type semiconductor area having p-type conductivity. A plurality of this kind of p-type semiconductor areas are disposed repeatedly in a light advancing direction of the optical modulator waveguide. Holes generated by light absorption of input light in a semiconductor optical waveguide layer are pulled out from an electrode shared with the second n-type semiconductor layer via the p-type semiconductor areas. In this way, accumulation of the holes in the semi-insulating clad layer serving as the barrier layer can be prevented or reduced.

    Abstract: 本発明は、ニオブ酸リチウムのような電気光学基板(100)と、基板内に形成された光導波路(200)と、導電性の脚(350A)によって基板から持ち上げられたマイクロ波伝送ライン(300)を含む電極構造体とを有する電気光学変調器に関する。 一実施形態では、基板と伝送ラインとの間に低誘電定数のバッファ層(400)が配置されている。 導電性の脚は、伝送ラインからバッファ層を通って導波路の方向に基板表面まで延びている。 マイクロ波伝送ラインは、電気的伝搬速度が最大になるような距離で基板から持ち上げられている。 高速の電気速度は導電性の脚によって生じる負荷キャパシタンスにより相殺され、それにより、伝送ライン上の電気速度が低下して光速度と整合する。 対向する導電性の脚の対は、強力な電界を供給して光信号を変調する。
