Schematic image of the analyzed PC structure with elliptical air holes: (a) PC with no phase shift; (b) PC with -phase shift. The thin arrows stand for the electric field . The thick arrows stand for the phases of the emitted field from the surface on both sides of the shift after destructive interference.
Time-averaged intensity of the electric field in wave vector space for an elliptical ratio of 80%: (a) for PC with no shift; (b) for PC with -phase shift.
Time-averaged intensity of the electric field in wave vector space: (a) Distribution for with no shift; (b) distribution for with the phase shift; (c) distribution for with no shift; (d) distribution for with the phase shift. The peak values in (c) and (d) are normalized to 1. The peaks in (a) and (c) are magnified by the factors indicated in the figures.
(a) Dependence of the linear polarization strength on the elliptical ratio; (b) the dependence of the 2D optical coupling factor on the elliptical ratio. The filling factor is 15.7% in all cases.
