我们报道了一种低成本，简单的光/电电路板（OECB）的发展，使用多模聚合物波导的FR 4印刷电路板（PCB）。该OECB的设计仅使用45 °端波导来直接在光学器件和波导之间耦合和解耦光信号。45度反射镜是使用准分子激光工艺在多模波导上形成的，在回流温度下具有温度稳定性。使用粘合剂将光波导连接到FR 4 PCB中的切割通道，以形成完全平面的电路。这使得激光二极管和光电二极管能够使用精密倒装芯片技术直接组装在波导的输入和输出上方，从而提供良好的对准精度。这有助于提高电路的机械可靠性，并最大限度地减少装配要求。最重要的是，所使用的所有电子和光电器件都是市售组件。在本文中，我们报告的设计细节，仿真结果，和测试结果。
We report the development of a low cost, simple optical/electrical circuit board (OECB) using multimode polymer waveguide on FR4 printed circuit board (PCB). The design of this OECB uses only a 45deg-ended waveguide to couple and decouple the optical signal directly between the optical devices and the waveguide. The 45deg mirror is formed using excimer laser process on a multimode waveguide with temperature stability at reflow temperature. The optical waveguide is attached to a diced channel in the FR4 PCB using adhesive to form a completely planar circuit. This allows the laser diode and the photodiode to be assembled directly above the input and output of the waveguide using precision flip chip technology, which provides good alignment accuracy. This helps to increase the mechanical reliability of the circuit and minimize assembly requirements. Most importantly, all the electronic and optoelectronic devices used are commercially available components. In the paper, we report the details of the design, simulation result, and the testing results.
