Dr. Xiaolong Hu is a professor in the School of Precision Instrument and Optoelectronic Engineering at Tianjin University. He obtained his B. S. and M. S. degrees from Tsinghua University in 2003 and 2006, respectively, and obtained his Ph. D. degree from the Massachusetts Institute of Technology (MIT) in 2011. Professor Hu’s research focuses on nanophotonic devices and nanofabrication, and is also relevant to mode-division multiplexing technology and stretchable electronics. In his Ph. D. thesis work at MIT, he did an early demonstration of a fiber-coupled SNSPD system with efficiency exceeding 20%, applied the SNSPD system in quantum optic measurement with collaborators, and proposed waveguide-integrated SNSPDs. Recently at Tianjin University he reported on two mechanisms of device timing jitter of SNSPDs, proposed and demonstrated the fractal SNSPDs with low polarization sensitivity, proposed the superconducting nanowire multi-photon detectors integrated with current reservoirs. As a major co-inventor, he co-invented a nanofabrication process to integrate commercial electronic and optoelectronic components into mechanically stretchable systems. He established and experimentally validated a model describing Rayleigh scattering in few-mode optical fibers. He is now serving as an associate editor of Optics Continuum, a committee member of the superconducting-electronics sub-society, Electronic Society of China, and the faculty advisor for the Optica (formerly OSA) Student Chapter and the SPIE Student Chapter at Tianjin University.
