報告簡(jiǎn)介：Targeting the huge unused bandwidth of current telecommunication networks, Bi/Er co-doped silica optical fibers (BEDFs) have been proposed and developed for ultra-broadband, high-gain optical amplifiers covering 1150-1700 nm range. In this presentation, Dr. Luo will introduce the fabrication of ultra-broadband luminescent BEDF and bismuth/erbium/ytterbium co-doped optical fiber (BEYDF) with modified chemical vapor deposition (MCVD) and in situ doping techniques. Several novel and sophisticated techniques have been developed for the fabrication and characterization of new active fiber. For the modification of performance of active fibers, post-treatments, like high temperature, radiation and laser, have been introduced to treat them. There have been some photonic applications such as fiber sensing, fiber gratings, fiber amplification and fiber lasers, etc., though there remain many fundamental scientific and technological issues and challenges.
針對當前電信網(wǎng)絡(luò )的巨大未使用帶寬，業(yè)界提出并開(kāi)發(fā)了Bi/Er共摻雜石英光纖（BEDF），用于覆蓋1150-1700 nm范圍的超寬帶/高增益光放大器。在本報告中，羅博士將介紹超寬帶發(fā)光BEDF和鉍/鉺/鐿共摻雜光纖（BEYDF）的制造，該光纖具有改進(jìn)的化學(xué)氣相沉積（MCVD）和原位摻雜技術(shù)，已經(jīng)開(kāi)發(fā)出的幾種新穎和復雜的技術(shù)來(lái)制造和表征新的活性光纖。同時(shí)，為了改變活性光纖的性能，已經(jīng)引入了諸如高溫、輻射和激光的后處理來(lái)對其進(jìn)行處理。盡管仍然存在許多基本的科學(xué)技術(shù)問(wèn)題和挑戰，但現實(shí)中仍存在一些光子應用，例如光纖傳感、光纖光柵、光纖放大和光纖激光器等。
