  2. The transportation of the electron beam in the waveguide guided by low magnetic field is studied and some valuable results are obtained

    對環形電子束在低磁場中的傳輸進行了粒子模擬和理論分析,得出了一些有意義的結論。
  3. 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

    本文主要藉助這種改進的fd _ bpm演算法,對兩種結構的光分路器(直y型光分路器,上升正弦型光分路器)進行了器件設計的軟體模擬,包括對兩種結構光分路器傳輸場進行模擬,並對兩種結構光分路器的重要參數,如波導寬度,分叉角,縱橫比,損耗進行了模擬計算;得到了一些有價值的優化波導結構參數值,根據這些優化值設計製作了光刻模板。
  4. The angle spectrum of inputting optical signals is received by the input surface of arrayed waveguides. whereas the diffraction process of light beam outputed in slab waveguide is a process of " composing frequency and generating image ". the reason that fraunhofer diffractive pattern can be gained on outputting waveguide surface is that output ends of arrayed waveguide distribute on the arch structure which leads bent phase factor to offset the quadratic phase factor in fresnel diffraction

    輸入平板波導內光束的衍射過程是「分頻成譜」的過程,在陣列波導的輸入面接收到的是輸入光信息的角譜;而輸出平板波導內光束的衍射過程則是「合頻成像」的過程,正是由於陣列波導輸出口排列分佈在圓弧形結構上,其彎曲位相因子消去了菲涅耳衍射中的二次位相因子,從而在輸出波導面上能夠得到夫瑯和費衍射圖樣。
  5.
