主　　题：Absorption through a coupled optical resonance in a horizontal InP nanowire array InP 

摘      要：We study through electromagnetic modeling the absorption of light of a given wavelength in an array of horizontal In P nanowires of diameter less than 100 nm. Such absorption is performed most efficiently by using polarized light and by exciting a coupled optical resonance in a sparse array. In that case, we excite a resonance in the individual nanowires and couple the resonances in neighboring nanowires through a lattice resonance of the periodic *** such a resonance, an array with nanowires of 80 nm in diameter can absorb more than eight times more strongly than a tight-packed array, despite containing a seven times smaller amount of the absorbing InP material.
