Abstract
Designs for photonic nanojet (PNJ) generators are examined. The maximum intensity of the PNJ is used as an objective for optimization under the constraint of maximum refractive index and fixed generator size. Building on the work of Patel et al. with a generator of a step-index profile across tangent microspheres, we propose a gradient index (GRIN) design. Our design has a higher intensity focus yet requires lower index contrast. This eases fabrication while improving resolution in applications including photolithography.
