摘要：
Analytical effective refractive index (n(eff)) calculations for unit cells of ring/spoke structures, fabricated by two-photon polymerization, are undertaken. Geometrical parameters (spoke width, spoke length and number of spokes) are varied. Resulting neff values are mapped to a hyperbolic-secant profile resulting in a gradient index optic.
