Vol.121, No.6 (2010), 567-574003040262-s2.0-77549088496https://repository.li.mahidol.ac.th/handle/20.500.14594/29095We first propose a concept of a new interferometric technique, where the ultra-narrow spectral width of light pulse generated by using the micro-ring resonators can be used to perform the ultra-high-resolution interferometer. Firstly, the SHG using micro-ring resonators is analyzed and described, Secondly, the increasing in optical path difference (OPD) depends on the full-width at half-maximum (FWHM) width of the generated pulse is discussed. Finally, the optimum entangled photon visibility can be formed the quantum interferometer where the measurement resolution of 10-5-10-7in term of birefringence is achieved. The use of such systems for quantum interferometer, high-resolution interferometer and surface characterization are described. © 2008 Elsevier GmbH.
