Abstract: Abstract We numerically demonstrate mid-infrared supercontinuum generation in dispersion-engineered chalcogenide glass channel waveguide. The proposed ridge waveguide consists of arsenic pentasulfide (As2S5) strip deposited on magnesium fluoride (MgF2) substrate and air acting as an upper… read more here.
