  1. By combining do lens elements with normal refraction elements, color aberration is corrected to levels even higher than is possible with fluorite elements

    Do鏡片與普通的折射玻璃結合在一起，色散的校正水準甚至高於螢石鏡片。
  2. Abstract : it is observed that the sommerfeld ' s formula for a progressive spherical wave is not covariant with respectro the rotation of the coordinate system. it contains complex partial waves that are not physical. the standing wave representation of the same formula is shown to be covariant and physical. it is applied to solve the boundary value problem of fiber optics. the radiation modes as well as the guided normal modes are obtained in closed forms. the intensity distribution in various modes is obtained. it is remarked that the mode of critical refraction is missing

    文摘:說明了球面行波的索末菲公式在坐標轉動下不協變.證明了球面波的駐波表示是協變的，因而是一個物理的關系式，故適用於圓柱坐標中各類波動方程的定解問題.作為一個例，應用於光纖光學，導出了受導簡正模和輻射模的表達式，以及各模式的強度分佈
  3. They are new type of passive optical components, which are based on the periodical distribution of refraction index in fiber core. fiber gratings have several distinguished advantages over normal fibers

    它是利用光纖材料的光敏特性在光纖的纖芯上建立的一種空間周期性折射率分佈，其作用在於改變或控制光在該區域的傳播行為方式。
