Boubacar Kante is the inaugural Chenming Hu endowed Chaired Associate Professor at UC Berkeley. His multidisciplinary research interests are in the areas of wave-matter interaction from microwave to optics and related fields such as antennas, nanophotonics, novel materials, and quantum optics.
Boubacar Kanté is best known for his invention of the Berkeley Surface Emitting Laser (BerkSEL) that overcomes a six-decade long challenge in wave-physics on how to increase the size of a lasing cavity while maintaining it single mode. He proposed and demonstrated the world first topological laser based on the quantum Hall effect for light, a demonstration selected as one of the top 10 discoveries by Physics World in 2017. He demonstrated the world first bound state in continuum (BIC) laser, where he highlighted the unique scaling of BIC cavities for enabling compact and efficient light sources. He also demonstrated the first single-mode valley-Hall topological laser. His group hold the world record for plasmonic nanosensing (immuno-assay nanosensing) using a scheme he proposed for the implementation of singularities of open systems known as exceptional points. He also holds the world record for the bandwidth and efficiency of planar structured lenses, a structure he named “the Fishnet-Achromatic-Metalens (FAM)”. Prof. Kanté demonstrated the first non-magnetic metamaterial invisibility cloak. He introduced the notion of symmetry/parity of ring resonators, an idea used to prove that closed rings, previously believed incapable of producing artificial magnetism, can make ultra-broadband negative index in metamaterials.
