  3. In the attenuated - total - reflection ( atr ) multi - layer structure, light reflectivity can be highly dependent on layer parameters such as the layer thickness and refractive index. a tiny change in these parameters can lead to a large change in the light reflectivity

    衰減全反射（ atr ）結構是光學上一種較為特殊的反射型結構，在一定的條件下，反射光的空間強度和頻譜成分都會受到結構參數的影響和控制，同時反射光也攜帶上了結構本身的信息。
  4. In this paper, some investigation and design as following. have been carried out on er - yb codoped phosphate glass waveguide laser first, three primary performance parameters of er - yb waveguide laser pump threshold power ; output power and slope efficiency have been commulated and analysed theoretically based on er ~ ( 3 + ) - yb ~ ( 3 + ) energy configuration ; rate equation of stable state and transmitting equation. the influences of er - yb ions concentration ; enabled waveguide length ; light dot radius of signal light and pump light ; reflectivity of output lens on three above parameters have been researched

  5. The photo - induced phase transition of the different light intensities, photo - energies and directions of the polarized light is investigated. it suggested that the photo excites the down spin eg electrons and destroys the spin order system of the thin films. the relation between the he - ne laser reflectivity of the thin film, applied current and resistance was analyzed by the optics theory of solid state physics

    光子通過激發e _ g向下電子的躍遷，從而改變材料自旋極化方向，影響體系的輸運行為；首次研究了cmr薄膜的激光反射率和偏置電流的關系，並用固體光學理論對其定性分析，表明反射率的變化是由於電場引起材料的晶格畸變，改變了極化率，從而導致材料的折射率和反射率發生改變。
  6. By computer simulation and calculation, the relation between the reflectivity and the structure parameters of such gratings are presented. these results show that a glass grating can achieve antireflection over almost the whole visible light waveband for unpolarized light, while a silicon grating with a columned grid substrate also can achieve low reflectance over as a broad field of view as a tapered silicon grating structure can, but it can be fabricated more simply

    理論分析發現硅基底的圓柱形網格光柵能夠在比較大的視場獲得比較低的反射率，具有特定參數結構的低反射率硅基底圓柱形網格光柵可以獲得與專為大視場設計的金字塔形網格光柵相同的視場角，但它的製作更容易，更簡單。
