    • Optical waveguide coupling ratios can be modified for a package by providing a substrate with a photonic circuit disposed on a first section of the substrate and a plurality of optical waveguides formed in glass disposed on a second section of the substrate, the waveguides being connected to the photonic circuit, adjacent ones of the waveguides having a fixed coupling ratio. A three-dimensional region of the glass abutting an end of one or more of the waveguides is lased to change a refractive index of the glass in each three-dimensional region, and thereby extend a length of each waveguide abutting one of the three-dimensional regions so that the coupling ratio between that waveguide and an adjacent waveguide is changed as a function of the extended length. The lasing is controlled based on feedback so that each coupling ratio changed by the lasing varies by less than a target amount.
    • 光波导耦合比可以通过提供衬底上设置在衬底的第一部分上的光子电路和在衬底的第二部分上形成的多个形成在玻璃上的光波导来修改封装,波导连接到 光子电路,相邻的波导具有固定的耦合比。 靠近一个或多个波导的端部的玻璃的三维区域被改变以改变每个三维区域中的玻璃的折射率,从而使每个波导的长度相对于三维 区域,使得该波导和相邻波导之间的耦合比作为延长长度的函数而改变。 基于反馈来控制激光,使得由激光改变的每个耦合比率变化小于目标量。

    • An optical physical interface module is provided which includes a first optical physical interface, a second optical physical interface and one or more optical components. The first optical physical interface is configured to plug into a first connector and communicate optical signals toward the first connector. The second optical physical interface is configured to receive a second connector and communicate optical signals toward the second connector. The one or more optical components are operable to process optical signals between the first and second optical physical interfaces. The optical physical interface module may be provided at the edge of a circuit board so that the circuit board has an optical interface for external communication. The optical physical interface module may be a stand-alone module or integrated into a connector of an optical cable, among other configurations.
