Based on the aberration theory of AWG, a new-type flat-field AWG is designed. The focal signals of all wavelengths of operation are focusing along a straight line perpendicular to the propagation direction. Three stigmatic points restrain three dominant geometry parameters. Furthermore, a new-type flat-field wavelength router with both flat input field and flat focal field is also designed.

基于阵列波导光栅的像差理论，利用三个无像差点约束三个主要结构参量，设计了新型平场聚焦阵列波导光栅，使得所有工作波长的输出信号都聚焦在与光束传输方向垂直的直线上，并进一步将其拓展为同时具有平输入场和平聚焦场的新型平场波长路由器。

ABSTRACT Sublevel caving method is a high efficiency mining method for underground mine, it has many advantages, such as a simple mine stope, good work condition, high mechanization and low mining cost. Up to now, this method has been used in more than 85 percent of all underground iron mine.

无底柱分段崩落法是一种高效率的采矿方法，具有采场结构简单，作业条件好，机械化程度高，回采强度大，采矿成本低等优点，迄今应用该采矿方法采出的矿石量约占我国地下铁矿采出矿石总量的85％。

The EDFL is structured by insertion of three different short passive subring cav it ies, which serve as mode filters, into the main cav it y, and it is combined w it h a fiber Bragg grating, the MRCs resonator can make SLM lasing.

这种激光器通过在主环形腔中插入充当模式滤波器的三个长度不等的无源次级环形腔，并结合腔内光纤布拉格光栅形成多环形腔掺铒光纤激光器结构，多环形谐振腔可保证激光器的单纵模输出。
