Deskripsi
Designing high performance THz pixelless imaging devices is nowadays challenging due to the inability to obtain normal incidence excitation using a grating coupler. Here, the authors report a broadband GaAs HIWIP-LED THz-NIR up-conversion imaging device avoiding the use of any grating coupler.
