Fabrication Techniques and Applications of Metal Manocluster swith Desirable Characteristics

本论文主要研究了纳米团簇的新型光学器件，包括（1）图案化超薄光学偏振膜和（2）多波长光学数据存储介质等。对于图案化超薄光学偏振膜，我们制备了波长为800 nm的偏振膜，并通过高功率CO2激光的照射成功地将其图案化。对于多波长光存储介质，我们已经证明了金属岛薄膜是一种非常有趣的用于一次写入多波长三维光盘的光存储介质。基本操作已被实验证实，使用铝-银化合物金属岛膜为490 nm和银-金化合物金属岛膜为810 nm。此外，我们提出了新的波导偏振器使用人工双折射介质，包括周期性介质多层膜，多孔介质，和柱状介质。

In this work, we have investigated novel optical devices using nanoclusters including (1) patterned ultra-thin optical polarizing films, and (2) multiwavelength optical data storage media, etc.For the patterned ultra-thin optical polarizing films, we have fabricated the polarizing films for the wavelength of 800 nm and have successfully patterned those by the irradiation of high-powered carbon dioxide laser. The patterned polarizing would be useful for optical computing and sensing thechnology.For the multiwavelength optical data storage media, we have demonstrated the metal island films are very interesting optical data storage media for write-once multi-wavelength 3-D optical disks. The basic operation has been experimentally confirmed using aluminum-silver compound metal island films for 490 nm and silver-gold compound metal island films for 810 nm.In addition, we proposed novel waveguide polarizers using artificial birefringent media, including periodic dielectric multilayers, porous dielectric media, and columnar dielectric media.
