Patent number: 7957250Abstract: A micro optical head is provided, which provides sub-wavelength focusing spot and very long depth of focus. The optical head includes a transparent substrate, an opaque film, and at least one sub-wavelength annular channel. After coherent light transmits the transparent substrate supporting the optical head and passes through the appropriately designed sub-wavelength annular channel, the transmitted light can overcome the diffraction limit, and the transmission energy is improved efficiently. The transmitted light converges after a certain distance behind the optical head and forms a sub-wavelength-scale beam that maintains a very long distance without divergence.Type: GrantFiled: December 20, 2007Date of Patent: June 7, 2011Assignees: Industrial Technology Research Institute, National Taiwan UniversityInventors: Chih-Kung Lee, Ding-Zheng Lin, Tsung-Dar Cheng, Chin-Kai Chang, Chih-Hao Chen, Chau-Shioung Yeh, You-Chia Chang

Publication number: 20110036818Abstract: An optical etching device for laser machining is provided and includes a laser light source and an optical head. The laser light source emits an incident beam. The optical head includes a transparent substrate, an opaque film and a sub-wavelength annular channel. The laser energy tolerance of the transparent substrate ranges from 8 J/cm2 to 12 J/cm2. The opaque film has a first surface and a second surface opposite to the first surface. The transparent substrate is adhered to the first surface. The sub-wavelength annular channel is formed in the opaque film and extends from the first surface to the second surface so that the incident beam from the transparent substrate generates a surface plasma wave on the opaque film.Type: ApplicationFiled: May 5, 2010Publication date: February 17, 2011Applicant: NATIONAL TAIWAN UNIVERSITYInventors: Chih-Kung Lee, Jyi-Tyan Yeh, Ding-Zheng Lin, Tsung-Dar Cheng, Chin-Kai Chang

Patent number: 7792006Abstract: 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: GrantFiled: May 29, 2007Date of Patent: September 7, 2010Assignee: Industrial Technology Research InstituteInventors: Chih King 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
