Abstract :
A back metallic binary-rectangle grating is proposed to realize absorption enhancement through introducing plasmonic modes and cavity resonance modes. The grating contains a secondary grating whose height is optimized. Adding the structure can enhance absorption by a factor of 2.6 at λ = 915 nm and for the wavelengths in the range 550-790 nm, 875-900 nm the absorption is also enhanced.
