Fig. 7.8 The spectral enhancement factors of the OSC with NSPs are embedded into the active
layer. The angular responses of the OSC for the vertical ð 0 Þ and oblique ð 60 Þ incidences are
also shown: a separated small NSPs; b close-packed small NSPs; c separated large NSPs; d close-
packed large NSPs. 2011 AIP; Ref. [ 30 ]
