摘要 | In an embodiment, light from a single mode light source may be deflected into a low index contrast (LIC) waveguide in an opto-electronic integrated circuit (OEIC) (or "opto-electronic chip") by a 45 degree mirror. The mirror may be formed by polishing an edge of the die at a 45 degree angle and coating the polished edge with a metal layer. Light coupled into the LIC waveguide may then be transferred from the LIC waveguide to a high index contrast (HIC) waveguide by evanescent coupling. |
其他摘要 | 在一个实施例中,来自单模光源的光可以通过45度镜偏转到光电集成电路(OEIC)(或“光电芯片”)中的低折射率对比(LIC)波导。可以通过以45度角抛光模具的边缘并用金属层涂覆抛光的边缘来形成镜子。然后,耦合到LIC波导中的光可以通过渐逝耦合从LIC波导传输到高折射率对比(HIC)波导。 |
主权项 | An apparatus comprising: a die including a waveguide substantially parallel to a surface of the die, and a mirror to couple light directed substantially parallel to the surface of the die into the waveguide, the mirror including a polished edge of the die covered with a reflective material. |
