边发射激光器 meaning in English

eels edge-emitting laser

The principle advantages of vcsels over conventional edge - emitting lasers lie in ultralow threshold current , small far - field divergent angle , high modulation frequency , potential for wafer level testing and the ease for single longitudinal mode operation and two - dimension integration . as a result they show considerable promise for applications such as optical fiber communication , parallel optical interconnects , optical information processing and neural networks , etc . a direct coupling theoretical model in quasi - three - dimension for the gain - wave guide vertical - cavity surface - emitting lasers has been created in this paper
它与传统的边发射激光器相比具有更优越的特性，例如，具有极低的阈值、较小的远场发散角、调制频率高、易实现单纵模工作和二维集成，无须解理封装即可进行在片测试等，所以，它被广泛应用于光纤通讯、并行光互联、光信息处理、光神经网络等领域。
