中文摘要

我們提出一個多波長且波長可切換的 C-band 摻鉺光纖雷射。其雷射共振腔是以布拉格式光纖光柵以及Circulator Loop Mirror 所構成。藉由串接多個不同 C-band 波長的布拉格式光纖光柵在單一增益介質中,且調整共振腔中損耗可達成多波長切換功能。實驗證明此種雷射具有中等功率、高穩定度(4 ± 0.04 dBm),全 C-band的波長可調範圍,以及可作為 DWDM高密度光纖通訊系統之光源的切換波長精確度(0.15 nm)

英文摘要

A multiwavelength switchable erbium doped fiber laser (EDFL) employing fiber Bragg gratings is proposed in this paper. The spectral profile for the active fiber in the EDFL is specifically tailored to enhance the switching capability between two closely-spaced wavelengths. The experimental results demonstrate that the proposed EDFL has advantages of
moderate power with high stability (40.04 dBm), wide wavelength switchable range (covering the C-band), high side-mode suppression ratio (>37 dB),
and narrow separation between two switchable wavelengths(0.15 nm).
