Publication number: 20080002556Abstract: The present invention provides an optical head with a single or multiple sub-wavelength light beams, which can be used in arenas such as photolithography, optical storage, optical microscopy, to name a few. The present invention includes a transparent substrate, a thin film, and a surface structure with sub-wavelength surface profile. The incident light transmits through the transparent substrate, forms a surface plasma wave along the sub-wavelength aperture located within the thin film, and finally re-emits through spatial coupling with the sub-wavelength profile of the surface structure. As the coupled re-emitting light beam or light beams can maintain the waist less than that of the diffraction limit for a few micrometers out of the surface with sub-wavelength profile in many cases, this invention can have applications ranging from micro or nano manufacturing, metrology, and manipulation by using light beams with waist smaller than the diffraction limit.Type: ApplicationFiled: May 29, 2007Publication date: January 3, 2008Inventors: Chih-Kung Lee, Liang-Bin Yu, Jiunn-Woei Liaw, Ding-Zheng Lin, Jyi-Tyan Yeh, Yu-Tsung Chiu, Chun-Ti Chen, Chyan-Chi Wu, Chau-Shioung Yeh, You-Chia Chang, Kuo-Tung Huang, Yi-Chun Chen, Yeong-Feng Wang

Patent number: 6927911Abstract: The light-guide module for emitting particular polarized light beams includes a splitter for separating non-polarized light beams, a transformer for converting polarization of light beams, and a non-polarized light source. The non-polarized light source emits light beams. Particular polarized light beams pass the splitter and other light beams are reflected by the splitter. Polarizations of reflected light beams and of light beams emitted by the non-polarized light source are converted by the transformer so as to separate the light beams later. Thus the light-guide module for emitting particular polarized light beams loses relatively little light energy.Type: GrantFiled: June 9, 2003Date of Patent: August 9, 2005Assignee: Industrial Technology Research Institute/Material ResearchInventors: Ming-Lang Tsai, Chun-Hsiang Wen, Hui-Lung Kuo, Kuo-Tung Huang, Yaw-Ting Wu, Ying-Chiang Hu, Chih-Kng Lee, Liang-Bin Yu, Ping-Chen Chen, An-Shun Liu
