 技術摘要 / Our Technology： |
本發明提供一種多工(Multiplexing簡稱Mux)與解多工(Demultiplexing簡稱Demux)的光學次模組裝置；在發射端(TOSA，Transmitter of Optical Subassembly)部分，四顆不同波長的雷射光源分別經由透鏡(球面鏡、非球面鏡)導成近似平行光，並經過薄膜濾波片的耦光，最後再經過透鏡(球面鏡、非球面鏡)耦合到光纖裡；在接收端(ROSA，Receiver of Optical Subassembly)的部分，光纖導出的光經由透鏡(球面鏡、非球面鏡)導成近似平行光，再經過薄膜濾波片的分光，由薄膜濾波片所分出的光訊號分別經過透鏡(球面鏡、非球面鏡)聚光到光檢測器(Photodetector)。本發明並具有一被動對位(passive alignment)與一主動對位(active alignment)的設計，以使整個光學次模組的光耦合效率最佳化。
Disclosed is an optical transceiver subassembly module for multiplexing and demultiplexing a plurality of channels of different wavelengths. The optical subassembly module includes a transmitter optical subassembly (TOSA) and a receiver optical subassembly (ROSA). For a TOSA, the optical signals emitted by four laser diodes of different wavelengths are combined into a multiplexed optical signal, through respective thin film filters and lenses, which is then coupled onto an optical fiber after passing through a focusing lens. For a ROSA, the input optical signal on the receiver end of the optical fiber is separated into multiple optical wavelength signals, through respective thin film filters and lenses, which are then registered by respective photo detectors. This optical subassembly module with compact star-shaped optics design, active and passive alignments is able to attain high coupling efficiency between optical signals and the optical fiber.
