Using 3D finite‐difference time‐domain modeling, a microsphere‐generating nanojet and gold nanoantenna gap are optimized to achieve 3D nanojet confinement to a subwavelength volume of about 0.009 µm 3 (wherein the edges of the volume are defined at 1/e 2 of the maximum electric‐field intensity) for an incident wavelength of 633 nm. © 2014 Wiley Periodicals, Inc.
