    • An optical waveguide device for loss absorption, and a fabrication method thereof, are provided. The optical waveguide device for loss absorption includes: a substrate of a predetermined material; a lower cladding formed on the substrate; an optical waveguide formed on the lower cladding, and formed of a material having a refractive index greater than a refractive index of the lower cladding; an upper cladding formed so as to completely cover the optical waveguide; and an absorption layer formed of a material having refractive index greater than a refractive index of the upper cladding, and formed on the upper cladding to a thickness which can absorb a reflected or radiated optical signal. As described above, an absorption layer capable of absorbing light is formed in the waveguide device upon fabricating the optical waveguide, thus minimizing or removing loss due to reflection and radiation of an optical signal.
    • 提供了一种用于损耗吸收的光波导器件及其制造方法。 用于损耗吸收的光波导装置包括:预定材料的基板; 形成在基板上的下包层; 形成在所述下包层上的光波导,并且由折射率大于所述下包层的折射率的材料形成; 形成为完全覆盖光波导的上包层; 以及由折射率大于上部包层的折射率的材料形成的吸收层,并且形成在上部包层上至可以吸收反射或辐射光学信号的厚度。 如上所述,在制造光波导时,在波导器件中形成能够吸收光的吸收层,从而最小化或去除由于光信号的反射和辐射引起的损耗。

    • A hybrid optical waveguide having linear and curved sections through which optical signals pass, includes: a planar substrate layer; a lower cladding layer formed of a material having optical transparency in a predetermined range of optical communication wavelengths, on the planar substrate layer; a core layer formed on the lower cladding layer where the optical waveguide is formed, the waveguide constituted of the linear section formed of a first optical polymer having a higher refractive index than the lower cladding layer and the curved section formed of a second optical polymer having a higher refractive index than the first optical polymer; and an upper cladding layer formed of a material having a lower refractive index than the first and the second optical polymers, surrounding the waveguide core layer. The optical waveguide having the linear and curved sections has reduced traveling losses and optical fiber coupling losses, and minimizes the size of the waveguide cross-section.
    • 具有光信号通过的线性和弯曲部分的混合光波导包括:平面基底层; 由在光学通信波长的预定范围内具有光学透明度的材料形成的下包层; 形成在形成有光波导的下包层的芯层,由具有比下包层更高的折射率的第一光聚合物形成的线状部和由具有第二光聚合物的第二光聚合物形成的弯曲部构成的波导构成的波导管, 比第一光学聚合物更高的折射率; 以及由包围波导芯层的折射率低于第一和第二光学聚合物的材料形成的上部包层。 具有线性和弯曲部分的光波导具有降低的行进损耗和光纤耦合损耗,并且使波导横截面的尺寸最小化。
