quantum metrology with parametric amplifier based photon correlation Interferometers
Nature Communications, 2014Co-Authors: F Hudelist, Jia Kong, Cunjin Liu, Jietai Jing, Z Y Ou, Weiping ZhangAbstract:Interferometers play a key role in precision measurements and metrology. Here, the authors demonstrate a new type of Interferometer that replaces the standard beam splitter elements with parametric amplifiers, which provides enhanced performance compared with a Mach–Zehnder Interferometer.

Atom-Light Hybrid Interferometer.
Physical Review Letters, 2015Co-Authors: Bing Chen, Cheng Qiu, Shuying Chen, Jinxian Guo, Li-qing Chen, Weiping ZhangAbstract:A new type of hybrid atom-light Interferometer is demonstrated with atomic Raman amplification processes replacing the beam splitting elements in a traditional Interferometer. This nonconventional Interferometer involves correlated optical and atomic waves in the two arms. The correlation between atoms and light developed with the Raman process makes this Interferometer different from conventional Interferometers with linear beam splitters. It is observed that the high-contrast interference fringes are sensitive to the optical phase via a path change as well as the atomic phase via a magnetic field change. This new atom-light correlated hybrid Interferometer is a sensitive probe of the atomic internal state and should find wide applications in precision measurement and quantum control with atoms and photons.

A Hybrid Fabry-Perot/Michelson Interferometer sensor usibng a dual asymetric core microstructured fiber
Measurement Science and Technology, 2010Co-Authors: Orlando Frazão, S. F. Silva, Jose Luis Santos, J. Vegas, J.m. Baptista, Philippe RoyAbstract:A hybrid Fabry-Perot/Michelson Interferometer sensor using a dual asymmetric core microstructured fiber is demonstrated. The hybrid Interferometer presents three waves. Two parallel Fabry-Perot cavities with low finesse are formed between the splice region and the end of a dual-core microstructured fiber. A Michelson configuration is obtained by the two small cores of the microstructured fiber. The spectral response of the hybrid Interferometer presents two pattern fringes with different frequencies due to the respective optical path Interferometers. The hybrid Interferometer was characterized in strain and temperature presenting different sensitivity coefficients for each topology. Due to these characteristics, this novel sensing head is able to measure strain and temperature, simultaneously.
