迴路型光纖雷射技術之研究

Abstract

本論文中提出一個穩定波長的可調變光纖迴路雷射架構、一個包含C波段與L波段的波長可調變架構、與一個S波段的波長可調變架構，藉由這三個架構的整合，使光纖迴路雷射的整體可調波段達130nm（1480nm∼1610nm），涵蓋整個光纖在1550nm中心的低損耗窗口，調變波長穩定時間可達2000秒以上，如此將有助於光纖迴路雷射在通訊應用上的實用化。

Fiber optical amplifier (the source power of the fiber ring laser) can extend the operation range from C band (1530nm ~ 1560nm) to L band (1560nm ~ 1610nm) or S band (1480nm ~ 1530nm). The conventional method tunes the output wavelength by using the single fiber filter, like a Fabry-Perot filter or tunable band-pass filter. In this essay, we bring up three new structures for those disadvantages, a wavelength-stable structure by Fabry-Perot laser diode, a wide-band tuning one by double filters, and another for S band wavelength output. By integrating the three structures, the new fiber ring laser system can tune at least 130nm (1480nm ~ 1610nm) and keep the wavelength stable more than 2000 seconds. It will be helpful to apply the new fiber ring laser in communication systems.
