    • A sub-mount for fixing a photodiode is provided with an opening for transmitting an light, which is incident from below a light receiving portion of the photodiode. A wavelength selective filter having a wavelength selective function via a dielectric multilayer film is fixed to the opening for transmitting the incident light. Further, a light shading structure for shading scattering light incident from the side of the photodiode is provided and the whole light-receiving-portion-side surface is covered by potting with an opaque resin for absorbing scattering light incident from the light-receiving-portion-side surface of the photodiode, whereby an optical receiver excellent in wavelength selectivity is formed.

    • An optical receiver includes a light-receiving part and a control part. The light-receiving part includes an APD, a PIN-PD, and a branching optical device. First signal light is incident on the light-receiving part and is divided into second signal light and third signal light which are incident on the APD and the PIN-PD, respectively, by the branching optical device. Due to this structure, the third signal light is incident on the PIN-PD without the quantity thereof being varied depending on the polarization state of the first signal light. The control part generates a supply voltage at which a desired avalanche multiplication factor is obtained in the APD on the basis of the output current from the PIN-PD. According to the above-described structure, the avalanche multiplication factor of the APD is accurately controlled on the basis of the output current of the PIN-PD.
    • 光接收器包括光接收部分和控制部分。 光接收部分包括APD,PIN-PD和分支光学装置。 第一信号光入射在光接收部分上,分别由分支光学装置分别入射到APD和PIN-PD上的第二信号光和第三信号光。 由于这种结构,第三信号光入射在PIN-PD上,其数量根据第一信号光的偏振状态而变化。 控制部分基于来自PIN-PD的输出电流产生在APD中获得期望的雪崩倍增因子的电源电压。 根据上述结构,基于PIN-PD的输出电流来精确地控制APD的雪崩倍增系数。

    • An optical transmission module includes plural optical transmission means (optical waveguides) whose end portions are exposed on a first end face thereof, and at least one of an optical transmitting section and an optical receiving section to each of which some of the optical transmission means are optically coupled. The remaining optical transmission means are exposed on a second end face opposed to the first end face. Only some of the plural optical transmission means are designed to have a communication facility at some position in the longitudinal direction thereof, while the remaining optical transmission means are designed to have the communication facility by being connected to post-stage optical transmission modules in the longitudinal direction. By multistage-connecting these optical transmission modules, plural optical transmission means and optical transmission modules can be collectively connected at a narrow frontage.
    • 光传输模块包括其端部在其第一端面上露出的多个光传输装置(光波导)和光传输部分和光接收部分中的至少一个,其中一些光传输装置是 光耦合。 剩余的光传输装置暴露在与第一端面相对的第二端面上。 多个光传输装置中只有一些被设计成在其纵向的某个位置具有通信设备,而剩余的光传输装置被设计成具有通过纵向连接到后级光传输模块的通信设备 方向。 通过多级连接这些光传输模块,多个光传输装置和光传输模块可以以较窄的正面集中连接。
