分布反馈半导体激光器 meaning in English

distributed feedback semiconductor laser
distributed-feedback semiconductor laser

In present commercial wdm systems , distributed feedback las ers ( dfb - ld ) are widely used as a single - mode tight source
在目前的wdm系统中，分布反馈半导体激光器( dfb - ld )已被广泛地用作单频光源。
A new laser source of optical communication , erbium - ytterbium codoped phosphate glass waveguide laser that was provided with more prominent performance than semiconductor distribution feedback ( dfb ) laser , has been investigated globally from 1990s . the laser can meet many rigorous demands of wdm systems . the 1 . 54 m laser emitted by the laser accords with the interrelated standard of international telecommunications union ( itu ) , therefore , a splendent foreground can be predicted about this kind of laser in future optical communication
基于铒、镱掺杂磷酸盐玻璃基片的光波导激光器是一种新型通信光源,具有传统的分布反馈半导体激光器所不能比拟的优点,能满足波分复用/密集波分复用技术对光源提出的诸多高新要求,所发射的1 . 54 m激光符合国际电信联盟规范,在未来光通信中有着广阔的发展前景。
