Nowadays SBG Labs produces head-up displays based on their switchable waveguide technology for the United States Army and the People's Liberation Army.
Its intended uses are focusing, imaging, light beam shaping, subwavelength optics, subwavelength light wave guiding, novel optical and magneto-optic data storage, light generation, microscopy, biophotonics, biological molecule sensors, and solar cells, as well as other applications.
In 2004, two French researchers, Etienne Le Coarer from Joseph Fourier University and Pierre Benech from INP Grenoble, coupled sensing elements to the evanescent part of stationary waves within a single-mode waveguide.
