Advanced Michelson Interferometers for Laser Interferometer Gravitational Wave Detection.
David Blair,

The detection of gravitational waves from black hole systems in the universe requires laser interferometers with exceptional specifications to enable them to detect gravitational wave induced strains with amplitude ~ 10-24 on a scale of kilometers. Such sensitivity requires very high laser power, mirrors with exceptionally low acoustic and optical losses, and exceptionally small figure errors. This must be combined with advanced quantum optics techniques such as optical squeezing. Currently three advanced detectors are preparing for observational runs at sensitivity sufficient to have a high probability of first detection. Much effort is underway to define the next generation of instruments which will be even more sensitive. This talk will focus mainly on the optical engineering challenges of gravitational astronomy, and on aspects of opto-mechanics that are relevant to other areas of physics and engineering.

Ciieng-Luen Zieng Award Candidate The accomplishment of optical monitoring for optical filter with luminescent layer
Ciieng-Luen Zieng,Yu-Jen Chen,Cheng-Chung Lee,Cheng-Chung Lee,

This article presents the fabrication of a narrow band pass filter, NBF, embedded luminescent layer under control of turning point monitoring. The stability of ion beam sputter deposition and self-compensation effect of a NBF monitored by turning point method well assist the deposition in spite of the process mixing dry and wet process. The experimental spectrum indicates that the error of center wavelength of the NBF is less than 1 nm.

Mu-Chi Liu Award Candidate X-ray Absorption Near Edge Structure of Silicon in Indium Arsenide
Mu-Chi Liu,Zhe Chuan Feng,Hao-Hsiung Lin,

We report on Si K-edge XANES of heavily Si doped InAs grown by GSMBE. A model of Si atom in group-III sublattice with +0.4 ionization and shorten second and third shell distances well fits the experimental result.

Ling-Chi Kuo Award Candidate Annealing effect on the mechanical loss of the ion beam sputtered nano-layer structures with application to the dielectric mirror for the laser interference gravitational wave detector
Ling-Chi Kuo,

This paper investigated thin film with low mechanical loss for high reflective mirror. A conventional quarter-wave-layer of TiO2 was replaced by a stack of TiO2/SiO2 in the nano-meter scale with total optical thickness remained quarter-wave. Thinner layer design has higher threshold temperature for crystallization. Mechanical loss of the 19-layers nano-layer stack was reduced with annealing at 300oC without crystallization.

Yu-Xen Lin Application of dynamic interferometry on thin film measurement
Yu-Xen Lin,Meng-Chi Li,Chung-Cheng Lee,

A method to measure the thickness and optical constant of thin-film based on dynamic interferometry is described. The thin film property is retrieved from reflectance and phase spectra. By micro-polarizer pixelated camera, a dynamic interferometry can be vibration-insensitive and capable to measure films with absorption as well as multi-layer films.
