在一种新的聚合物材料上刻写正弦相位波导光栅及其特性研究

Sine-phase waveguide grating is engraued on a new kind of polymer material through double-beams interference,which realizes grating coupled optical wave-guide.Conductive characteristical of optical wave-guide on different polarization incidence beam are investigated.Formation of grating is analyzed in theory as well,and propagation constant of optical wave-guide is calculated numerically in this article.The control of the wave-guide grating on guided-wave in modulation of light intensity and direction is discussed,the application of which in integrated optics is also noted.Finally,grating equation of arbitrary incident angle is analyzed.
