FIG. 1.

Cross section schematic of the GWF structure as fabricated. Here, denotes the period of the structure, and the numeric labels represent the (1) substrate film and (2) periodically modulated layer. The thickness of the layer is varied in the direction shown, such that an increase of thickness occurs every 556 periods.

(Color online) Intensity spectrum of the incident beam as recorded by the system for three wavelengths. Only regions that are resonant with the incoming beam present a dip in transmission. As the wavelength of the incident beam is changed, the resonance occurs at a different spatial location and presents a shifted transmission dip. The distance between adjacent pixels is .

(Color online) Position of the transmission minimum in pixel number (as determined by curve fitting) vs the incident wavelength. The solid line represents the line fit to the data and shows a high degree of linearity. The equation describes the line and the sensitivity characteristics of the system. (Inset): Lorentzian fit for the data point corresponding to .

(Color online) Time-resolved dispersion of the pixel for which minimum intensity was detected by the system for set wavelengths of (boxes) and (circles).
