摘　　要：报道了对熔锥型光纤反射器所作的较为系统的研究 .结果表明 :器件对某一波长的反射率 ,同时对另一波长的透射率均可大于 99% ,且器件的附加损耗小于 0 .1d B.文中着重阐述熔锥型反射器制造工艺和技术 ;The author reports a systematic research on the fused taper loop reflector. The reflector can be divided into two kinds. Simple loop reflectors only follow the reflective index at one wavelength. But complex loop reflectors produce not only the reflective index at one wavelength but also the transparency at another wavelength. Our research results have shown that the fused taper technology can manufacture a complex reflector with its reflective index at 1550 or 1053 nm better than 99% and its transparency at 980 nm better than 99%. The excess loss of the devices is less than 0.1dB. 980/1053 nm loop reflector can serve as a substitute for 1053 nm fiber grating. The above fact shows that the fused taper technology is a cheap and useful technology.
