由於高速大量資訊傳輸時代來臨,頻寬與資料量的需求量快速成長且已供不應求,所以為了解決大量高速傳輸所需要消耗的成本以及技術的突破,全世界無論業界或是學術單位已極力研發相關高速訊號的傳輸元件技術。對於資料中心伺服器間的資料傳送來說,使用光纖通訊是最佳選擇。因此若100 Gb/s光傳輸模組商業化之後,研發重點將轉為研發製作400 Gb/s 光傳輸模組,而眾多研究相關結果也在國際期刊及研討會中發表,但還是有許多挑戰需要突破。
本論文成功設計並優化單通道25 Gb/s 不歸零編碼訊號並載上高速電致吸收調變雷射,高速印刷版採用高頻板材來設計高 頻傳輸線以提高傳輸頻寬,並藉由差動訊號傳輸線減少共模雜訊降低阻抗匹配問題所造成的反射。由於在量測過程裡傳輸路徑上需經過上拉及電光吸收調變器電路,造成阻抗不匹配,因此本論文成功藉由模擬電路來驗證實驗結果並優化,藉由完成單通道25 Gb/s的成果進而完成設計單通道56 Gb/s之傳輸系統,設計結果將有利於後續實現8×56 Gb/s的400 Gb/s光傳輸模組。
High-speed information transmission stimulates the fast increasing bandwidth demands that becomes very challenging for modern communication device and system developers to achieve. The researchers are working hard to develop high-speed data transmission technologies that can meet the bandwidth growth demand while lowering the cost and energy consumption of the optical transceivers. For data centers, optical communication is the most effective solution. After 100 Gb/s transceivers were commercialized, 400Gb/s optical transceivers become one of the hottest research topic and many advancements are published in the journals and conferences. However, there are many challenges yet to be overcome.
In this thesis we successfully design and optimize the single-channel transmitters with high-speed electro-absorption modulation lasers for 25 Gb/s NRZ signals. The printed circuit board made of high-frequency material can increase the transmission line bandwidth. Differential-type transmission lines are designed to reduce the common-mode noise and impedance mismatch. The impedances mismatching by adding the pull-high and EAM circuits in the transmission path degrades the circuit performance. The high-frequency circuit design software is used to design and optimize the transmission lines and circuits We successfully demonstrated the single-channel 25 Gb/s optical transmitter and finish the design of circuit boards for single-channel 56 Gb/s transmitters. The design results will facilitate the subsequent implementation of 8×56 Gb/s transmitters for 400 Gb/s optical transmission.
