We report here an ultra-broadband linearly polarized(LP)LP01-LP11 mode converter operating at 1μm based on a long period fiber grating(LPFG)fabricated in a con
A sunlight communication system is proposed that uses Sr2Si5N8:Eu2+phosphors to concentrate sunlight signals in strong background light noise;thus,a wide spectr
We report an efficient mid-infrared extracavity optical parametric oscillator(OPO)based on the nonlinear crystal BaGa4Se7 pumped by a diode-side-pumped Q-switch
