The evolution of modern photonic technologies depends on the possibilities of obtaining large-scale photonic crystals cheaply and efficiently. Photonic crystals [1, 2] are periodic dielectric structures which are expected to play an important role in optics and optoelectronics due to their unique capability of controlling the emission and propagation of light via photonic band gap (PBG) and stop-gap effects. A comprehensive summary of the properties of various classes of PBG materials and their potential capabilities can be found in the literature, for example, books [3-6]. According to common knowledge, the wavelengths at which PBGs or stop-gaps open are close to the period of the dielectric lattice. At the same time, the most desirable spectral region for opto-electronic devices, including those based on photonic crystals, is in the visible and near-infrared wavelength range. Given this requirement, fabrication of structures periodic in one, two or three dimensions, and comprising many lattice periods, is not a trivial task. © 2006 Wiley-VCH Verlag GmbH &amp

3D Laser Microfabrication: Principles and Applications 1 - 388 2006年6月

記述言語：英語出版者・発行元：Wiley-VCH

A thorough introduction to 3D laser microfabrication technology, leading readers from the fundamentals and theory to its various potent applications, such as the generation of tiny objects or three-dimensional structures within the bulk of transparent materials. The book also presents new theoretical material on dielectric breakdown, allowing a better understanding of the differences between optical damage on surfaces and inside the bulk, as well as a look into the future. Chemists, physicists, materials scientists and engineers will find this a valuable source of interdisciplinary knowledge in the field of laser optics and nanotechnology. © 2006 Wiley-VCH Verlag GmbH &amp

Anisotropic etching of dielectrics exposed by high intensity femtosecond pulses

Saulius Juodkazis, Yuusuke Tabuchi, Takahiro Ebisui, Shigeki Matsuo, Hiroaki Misawa

Proceedings of SPIE - The International Society for Optical Engineering 5850 59 - 66 2005年

記述言語：英語

Post-processing of crystalline and glass materials after the exposure to femtosecond pulses was carried out by wet etching in water solutions of hydrofluoric acid. Crystalline sapphire and quartz showed high (larger than 100) anisotropy of etching, which allowed to develop high-aspect-ratio three-dimensional structures in the volume of those dielectrics. In silicate glasses the anisotropy of wet etching can be achieved by a proper selection of the overlap of adjacent pulses during recording, their energy, and focusing. Three-dimensional structures in silica glass (viosil with OH concentration below 1200 ppm) with a high aspect ratio of 100 were achieved. The mechanism of anisotropy in wet etching is discussed. Surface irradiation of sapphire at irradiance close to that of surface ablation recorded structural modifications resembling the ripples. Those structures were made observable only after wet etching. Period of the ripples can be explained by the recently presented theory (Y. Shimotsuma et al., Phys. Rev. Lett. 91 247405-1 (2003)). Sub-micrometer structuring of surface is demonstrated. Electron temperature at the moment of structure recording can be estimated from the period of ripples (for sapphire Te ≃ 11 keV was found).

年次大会講演論文集 : JSME annual meeting 2004 ( 4 ) 349 - 350 2004年9月

We report the method to fabricate micro-periodic structures using interference of femtosecond pulses (Wavelength 800nm; Pulse duration 150 femtosecond; Repetition Rate 1kHz). The method is based on pulse division using diffractive beam splitter and facilitates a spatio-temporal overlap of constituent pulslets. We demonstrate interference patterns formed by several pulslets and successful fabrication 1-, 2- and 3-dimensional micro periodic structures after a few minutes exposure of a commercial photosensitive resin (SU-8; Microlithography Chemical Corp.) with micrometer resolution.
