Shawn Yu Lin

Shawn Yu Lin (born in 1959 in Taiwan) is a Taiwanese American physicist, researcher, and educator who made pioneering contributions to the field of photonics and photonic crystals. He authored more than 250 technical papers.

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.

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.

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.

In 2007, Lin developed a meta material that constitutes “the blackest material known to science” (quote from Sir John Pendry). 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. A perfectly black material is the pinnacle of stealth technology because it cannot be seen.
