Figure 3. Light distribution according to wavelengths.

Figure 3

(a), An ITO-nanolens effectively modulates the visible light into the Si absorber. (b–f), FDTD simulation shows strong electric distribution with ITO-nanolens. (f–i), Incident light moves as plane waves through a flat ITO film. Strong electric peaks were observed along the (j) ‘a-line' and (k) ‘b-line'. (l) The flat ITO film shows only shallow electric fields for short wavelengths.
