In this paper, photonic nanojets resulting from corrugated cylinders (with irregular boundaries) under normally incident plane-wave illumination are studied. Different levels of corrugations induced at the boundaries of the dielectric microcylinders produce strong light focusing as well as a photonic nanojet with unique performance compared to perfectly smooth cylinders. The spectral element method is utilized in this study for the sake of high accuracy. Interestingly, we found that under some geometrical/material parameters one may not need a highly perfect cylinder in order to obtain a photonic nanojet. In addition, resonance behavior is reported and examined under larger variations in the parameters defining corrugated cylinders when compared with circular dielectric cylinders.
