In this talk, I will report our recent implementation of squeezed vacuum states at 1064 nm. With a bow-tie, optical parametric oscillator (OPO) cavity, and our home-made balanced homodyne detectors, noise reduction up to 10dB below the vacuum is measured. Applications of our squeezer to the gravitational wave detection will be discussed, with the collaboration with Japanese KAGRA project. At the same time, based on the niche of silicon photonics technologies and semiconductor industries in Taiwan, we will also introduce our proposal toward the implementation of scalable quantum photonic chips by integrating photonic qubits (single photon source, entangled photon pair, squeezed light), optical components based on silicon photonics, and photon detector arrays (single photon avalanche diode, homodyne detector).
Ray-Kuang Lee received his BS degree from department of Electrical Engineering of National Taiwan University (EE/NTU) in 1997, and his MS degree and PhD degree from Institute of Electro-Optical Engineering of the National Chiao Tung University (IEO/NCTU), in 1999 and 2004 respectively. He worked as an assistant scientist at National Center for High-Performance Computing, Taiwan, from 2001 to 2004, and as a visiting fellow at The Australian National University, Australia, in 2004. After his graduation he continued staying in IEO/NCTU as a postdoctoral fellow for seven months. Then he joined the Institute of Photonics Technologies of National Tsing Hua University as a faculty member at Aug. 2005.
