Congratulations to Claudia Imiolczyk, Moritz Floess, Simon Thiele and Harald Giessen for third place at OPN’s 15th annual After Image photo contest!
The image shows a freeform hologram directly 3D printed onto the tip of a single-mode optical fiber (Optica 7, 1279 (2020)). The freeform hologram displays the logo ‘OSA The Optical Society,’ independent of distance into the far field. The illumination wavelength is 520 nm.
