Professional career

After graduating from high school in Hualien, Taiwan, Lin attended NTU (Taipei, Taiwan) and received a B.S. in Physics in 1982. Subsequently, he attended UNC-Chapel Hill (Chapel Hill, North Carolina) and received an M.S. in Physics in 1986. Subsequently, he attended Princeton University (Princeton, New Jersey) and received a Ph.D. in Electrical Engineering in 1992.

In 1992, Lin joined the IBM T.J. Watson Research Center, Yorktown Heights, NY, as a Post-doctoral Fellow. In 1994, Lin joined Sandia, Albuquerque, NM, initially as a Member-of-Technical-Staff and later became a Distinguished Member-of-Technical-Staff. Lin also served as Research Professor (Physics) at Iowa State University, Ames, IA (2000-2004), Adjunct Professor (Material Science and Engineering) at Georgia Tech, Atlanta, GA (2002-2004), and Visiting Scientist (Electrical Engineering) at Princeton University, Princeton, NJ (2003-2004). In 2004, he joined RPI, Troy, NY, as a Chaired Professor of Physics.^[2]

Technical contributions

Since photonic crystals were first proposed in 1987, researchers have attempted to build practical three-dimensional photonic crystals (PCs). Lin and co-workers took photonic crystals down into the nano-realm using advanced semiconductor processing. In 1998, he developed the first large scale, 3-dimensional photonic crystal having a complete photonic band gap. In the same year, he demonstrated the first diffraction-less guiding and bending of light in a photonic crystal with a bending radius less than the wavelength. In 2015, Lin's research was reported as a candidate for the Nobel Prize in Physics.^[3]

In 2002, Lin created the first all-metallic photonic crystal. Upon thermal excitation, the photonic crystal reshapes the blackbody radiation spectrum and produces a coherent thermal emission. Extending this finding, Lin demonstrated that the intense photon field inside the crystal can be amplified through a non-equilibrium plasmonic excitation, leading to an order-of-magnitude enhancement of light emission beyond that predicted by the Planck blackbody radiation law.^[4][5][6]

In 2007, Lin developed a meta material that constitutes “the blackest material known to science” (quote from Sir John Pendry).^[7][8] Rather than examining a single nanotube, Lin studied the collective behavior of millions of nanotubes arranged in a "nano-forest." The blackest material was shown to absorb 99.97% of incident light, a Guinness world record.^[9][10] A perfectly black material is the pinnacle of stealth technology because it cannot be seen.
