"Researchers in USA and Saudi Arabia have been producing 610nm-wavelength red lasers with III-nitride nanowires (NWs) grown on silicon [Shafat Jahangir et al, Appl. Phys. Lett., vol106, p071108, 2015]. With a view to plastic fiber optical communication, the team from University of Michigan and King Abdullah University of Science and Technology (KAUST) studied the small-signal modulation characteristics."
"Other potential applications include mobile projectors, head-up displays in automobiles, and photodynamic therapy. Production on silicon promises lower-cost production and mass manufacturing."
