(a) Simulated parallel and perpendicular component of electric field intensity upon the resonant excitation of PSP at λ_ex = 633 nm depending on distance from the surface f. (b) Emission probability for a dipole representing the fluorophore emitting at λ_em = 670 nm to a cone above the gold surface with NA = 0.2 and NA = 1 as a function of distance f and dipole orientation. (c) Emission rate of a fluorophore emitting to NA = 0.2 at λ_em = 670 nm that is excited via PSPs at λ_ex = 633 nm for its parallel and perpendicular orientation and varied distance f.
