Polarization modulation in single-frequency He-Ne laser with an anisotropy feedback cavity
《Chinese Optics Letters》2012年第5期54-57,共4页陈文学 张书练 龙兴武 
supported by the National Natural Science Foundation of China (No. 61036016);the Scientific and Technological Achievements Transformation and Industrialization Project by the Beijing Municipal Education Commission
The polarization state is modulated by tilting birefringence component placed in the feedback external cavity.The variation of the polarization state in one period of modulation is found to be similar to sine wave.The...

A compact T-branch beam splitter based on anomalous reflection in two-dimensional photonic crystals被引量:1
《Chinese Optics Letters》2008年第10期709-712,共4页沈义峰 孙建 沈晓鹏 王娟 孙露露 韩奎 王国中 
the Science Foundation of China University of Mining and Technology under Grant No.OK061065
We project a compact T-branch beam splitter with a micron scale using a two-dimensional (2D) photonic crystal (PC). For TE polarization, one light beam can be split into two sub-beams along opposite directions. Th...
