本論文提出具光學透鏡連接器之光學軟性電路板設計適用於高畫質多媒體介面光學連接收發模組，此光學系統整合了高分子聚合物波導、45°微反射面、發射端雷射驅動晶片、垂直共振腔型面射型雷射、接收端轉阻放大器晶片、光偵測器於軟性電路板上，在軟性電路板的末端設計光學透鏡連接器，用於提升封裝容忍度以及與光纖端跳線接頭對接可快速完成光學對位。 經由光學模擬得到：傳輸端垂直面射型雷射出射，經由45微反射面轉折至高分子聚合物波導中，藉由光學透鏡連接器聚焦耦合進入多模光纖中，光學耦合效率達66.4%；接收端雷射光由多模光纖出射後，經由光學透鏡連接器耦合進入高分子聚合物波導中，最後再經由另一個45微反射面轉折進入光偵測器，其光學耦合效率達66.7%。傳輸端及接收端之光學串音干擾皆小於-30dB以下。 ;In this thesis, we proposed a design of optical system based on optical flexible printed circuit with optical lens connector for high definition video transmission interface. This optical system integrates polymer waveguide, 45 micro-reflecting surface, vertical-cavity surface emitting LASER (VCSEL), VCSEL driver IC, transimpedance amplifier (TIA), and photodetectors on a flexible printed circuit board. At the end of flexible printed circuit board, we design an optical lens connector to increase the packaging tolerance and connect with fiber-ended jumper connector to complete quickly optical alignment. According to the optical simulation results show that the optical coupling efficiency is around 66.4% from VCSEL passing through polymer waveguide and focusing into multi-mode fiber by optical lens connector. At receiving end the laser light is emitted from the multi-mode fiber, coupled into polymer waveguide by optical lens connector, and then finally passed through another 45 micro-reflecting surface to enter the photodetector. The optical coupling efficiency is around 66.7%. The inter-channel optical crosstalk at transmitting and receiving end are smaller than -30dB.
