- After that , this paper briefly introduced the optical splitter ' s characteristics of amplication by calculate a uniformly widen three energy level ratio equation and transmission equation . since providing these theories and results , this paper began to discuss on the material characteristic and the whole craft process in short
然后，本文通过计算均匀加宽三能级结构的速率方程和传输方程，对光分路器的增益放大特性作出了一般的理论分析。在有了以上的理论计算和分析之后，本文概括地讨论了制作光分路器的材料特性和工艺过程。 - In pon , the transmission of downlink signal from olt to onu is not complex . usually , the information destined for onus are combined into a multiframe at olt via tdm before reaching the feeder fiber , and then broadcast to each onu via the passive optical demultiplexor . upon receiving the downlink multiframe signal , each onu takes out the part of information for itself only
在无源光网络中， olt到onu的下行信号的传输过程较为简单，一般在olt将需要发送到各onu的信息采用时分复用的方式组成复帧送到馈线光纤，通过无源光分路器以广播的方式发送到每一个onu ， onu收到下行复帧信号后分别取出属于自己的那一部分信息。 - In this paper , the foundamental principles of fd _ bpm ( finite - difference beam propagation method ) used to simulate and calculate the process of beam propagation is first introduced . then ， the theory of boundary condition is carefully presented . based on those theories mentioned above , a new kind of fd _ bpm arithmetic is brought forward . compared with the traditional arithmetic , this one has much more advantages . in virtue of the new arithmetic , author accomplished the whole simulating designs with two kinds of optical splitter ( stright y - junction optical splitter and sine - type optical splitter ) , including propagation field simulating , vital parameter calculating , acquired some optimized waveguide parameters ， and finished the template by those results at last
本文主要借助这种改进的fd _ bpm算法，对两种结构的光分路器（直y型光分路器，上升正弦型光分路器）进行了器件设计的软件仿真，包括对两种结构光分路器传输场进行模拟，并对两种结构光分路器的重要参数，如波导宽度，分叉角，纵横比，损耗进行了仿真计算；得到了一些有价值的优化波导结构参数值，根据这些优化值设计制作了光刻模板。
