High data volume transmission.
隨著網路通訊的日漸普及，光纖網路也需要更加普及。被動式光纖網路具有安全、維護成本低、可塑性高三大特色，在實際應用上，高速資料量傳輸為被動式光纖網路的首要設計考量，垂直共振腔面射型雷射在1.55-μm單模情況下，因為其線寬非常窄的同調光源，現今被發展為高速資料量傳輸的發射機。鑒於單一雷射的頻率響應約10GHz，對於日益增長的資料傳輸不敷使用，而技術成熟的一階注入鎖模雷射雖然增加了頻率響應，不過也達到頻寬上的瓶頸。 With the increasing popularity of network communication, fiber-optic networks also need to be more popular. Passive optical fiber network has three characteristics of safety, low maintenance cost and high plasticity. In practical applications, high-speed data transmission is the primary design consideration of passive optical fiber network. Vertical cavity surface-emitting laser is in 1.55-μm single mode. Next, because of its very narrow linewidth coherent light source, it is now being developed as a transmitter for high-speed data transmission. Given that the frequency response of a single laser is about 10 GHz, it is not sufficient for ever-increasing data transmission, while the well-established first-order injection-mode-locked laser increases the frequency response, but also reaches the bottleneck in bandwidth.
然而直調雷射會產生嚴重的啁啾效應，限制了傳輸距離，在啁啾效應與色散交互作用下使得訊號失真。 However, direct-tuning lasers can cause severe ripple effects, limiting the transmission distance and distorting the signal due to the interaction of the ripple effect and dispersion.

為滿足與日俱增的通訊需求，光纖網路也日益普及，被動式光纖網路技術的成熟被逐漸關注於實現新世代寬頻網路，而新一代面射型雷射希望優化到幾十GHz調變頻寬，因此我們提出且證實了二階注入鎖模技術所建構之雙向被動光纖網路，結合了光學特性和面射型雷射優點，克服了雷射二極體的頻寬瓶頸，開啟了一個創新且可實施的高速系統，一階注入已被證實有效的增加面射型雷射頻率響應，為獲得更佳的被動式光纖網路傳輸成果，二階注入鎖模技術更加增強面射型雷射的頻率響應，近期直調式發射機價格低於外調式發射機因此更有吸引力的應用於被動式光纖網路，然而直調式發射機引起嚴重的啁啾效應且色散容限限制了傳輸距離，直調式發射機在光纖中產生的色散與啁啾效應交互作用下嚴重的限制了雙向被動光纖網路，造成無法忍受的失真，因此色散補償設備克服色散影響以及降低訊號失真，運用負色散光纖的特性改善直調式被動光纖網路中雷射的啁啾效應以及增加色散容限。 In order to meet the ever-increasing communication demand, fiber-optic networks are also becoming more and more popular. The maturity of passive fiber-optic network technology is gradually focused on realizing new generation broadband networks, and the new-generation surface-emitting lasers are expected to be optimized to tens of GHz. Therefore, we propose and confirm the two-way passive optical fiber network constructed by the second-order injection mode-locking technology, combining the optical characteristics and the surface-exposure laser to overcome the bandwidth bottleneck of the laser diode, opening an innovation and The implementation of high-speed systems, first-order injection has been proven to effectively increase the surface-exposure laser frequency response, in order to obtain better passive optical network transmission results, the second-order injection mode-locking technology enhances the frequency response of the surface-emitting laser. Recently, the price of direct-tuning transmitters is lower than that of external transmitters, so it is more attractive for passive optical networks. However, direct-tuning transmitters cause severe ripple effects and dispersion tolerance limits transmission distance. Direct-tuning transmitters The interaction between the dispersion generated in the fiber and the ripple effect severely limits the two-way passive optical network, causing unacceptable distortion. Dispersion compensation device to overcome the effects of dispersion and lower signal distortion, the use of negative dispersion characteristics of the fiber to improve the effect of chirp directly modulated laser passive fiber-optic network and an increase in the dispersion tolerance.
