1. A droplet of fluorescent molecules sits atop an array of nano-sized holes. An excitation laser from below is diffracted by the nanohole array, causing a "bloom" of internally reflected fluorescence within the droplet. The fluorescence from this array was used to calibrate the field-dependent aberrations of a super-resolved fluorescence microscope (see article submitted to Optica, 2015). Winner 2015 After Image photo contest. [Credit: Matthew D.

A tight camera aperture (f/32) creates a starburst image, while reflections within the camera system cause colorful ghost images of the partially eclipsed sun.

8. An optical fibre with 3D printed doublet Fresnel lenses is inserted into a water droplet to image the beam profile by an inverse microscope. A white light laser passed through the objective is used to align the fibre in respect to the objective and causes the blue colour of the lenses in the refracted image on the surface of the droplet. The image is taken by a 100mm f/2.8 micro lens on a DSLR (Canon 60D). The image is cropped, and gone under noise reduction and contrast enhancement. This photo involves equal contribution of two colleagues: measurement setup and fabrication by Dr Asa Asadollahbaik, photography by Mr Moritz Floess. The fabrication and design also includes the collaboration of Mr Simon Thiele and Ms Ksenia Weber. The image is taken at Optics Lab in 4th Physics Institute (Head of the Institute: Professor Harald Giessen), University of Stuttgart, Stuttgart.

16. A  blue/UV laser pointer was coupled into the handle of a cup, which guides it and feeds it into a fluorescing liquid that lights up in green colors. Surrounding Lab environment was darkened completely to highlight the effect. Mild post-processing was done (clipping, lifting the contrasts, noise correction). The image was taken in the lab at Leibniz-IPHT Jena. Winner 2018 After Image photo contest. [Credit: Tobias Tieß, Leibniz-IPHT]

18. A strip of LEDs creates white light by combing sets of red, green and blue LEDs placed together.  When imaged through the glass sphere in the center, the red, green and blue caustics are imaged to slightly different locations, due to the small distances between each color LED. Second Place 2016 After Image photo contest.

The cone uses total internal reflection of incident polarized light to easily generate white-light orbital angular momentum and radially polarized vector vortex beams.

21. Acoustic waves spectrally modulate supercontinuum light inside an acousto-optic tunable filter. The supercontinuum light interacts with resonating acoustic modes to produce 4-lobed orange, green and rainbow Schaefer-Bergmann diffraction patterns around the two spectrally modulated beams and undiffracted light. These optical patterns can quantitatively measure acoustic properties of crystals. Winner 2016 After Image photo contest. [Credit: Stephanie Swartz, University of Colorado at Boulder, USA]

22. Output light field of a tapered fiber probe illuminating a vial filled with water containing trace amounts of the dye Rhodamine 6B. Coupled into the fiber are green (532 nm) and blue (488 nm) laser light under slightly different angles resulting in colorful patterns due to effects of diffraction, interference, scattering and fluorescence. The result is reminiscent of a human iris with the pupil staring intently at the bottom of the glass vial from close proximity.  [Credit: Nils Frederik Hasselmann and Mathias Hünecke, Nonlinear Photonics, Münster University, Germany]

A piece of paper is used to trace out the beam in this long exposure image. Small rainbow beams can be seen shooting away from the stone, proof that the dispersive design of the diamond is doing its job. Second place winner, 2018 After Image photo contest.
