采用熔锥工艺研制成功这两种具有波谱特性的全光纤无源器件,与分立元什和镀膜工艺制作的同类器件相比,具有插损小、与光纤系统兼容、结构紧凑、性能稳定可靠、成本低等特点。这两种器件均工作在光纤通信实用波段(0.8～1.5μm),主要用于光纤波分复用系统、相干光纤通信系统等光纤通信技术及全光通信技术中作光信息的选频和滤波元件,其推广应用前景非常广阔。
The successful development of these two kinds of all-optical passive components with spectral characteristics by using the molten cone process has the advantages of small insertion loss, compatibility with the optical fiber system, compact structure, stable and reliable performance compared with the similar devices made by discrete elements and coating processes, Low cost and so on. Both of these devices work in the practical optical fiber communication band (0.8 ~ 1.5μm) and are mainly used for fiber-optic wavelength division multiplexing systems, coherent optical fiber communication systems and other optical fiber communication technologies and optical communication technology for optical information frequency selection and filtering Components, its promotion and application of a very broad prospect.
