Experimental W1 PCW transmission spectrum in water with coupled (a) L3 (b) L7 and (c) L13 microcavities. Experimental spectra showing shift of resonance mode closest to the band edge in (a), (b) and (c) in (d), (e), and (f) respectively in water (black) versus IPA (blue). Inset (e) magnifies the wavelength range.
