The Evolution Of Electric Light Bulbs

Imaged with the X-rays of Nikon's XTH225 CT system (left: Edison style incandescent light bulb, center: fluorescent light bulb, right: LED light bulb). In 2014, the invention of efficient blue light-emitting diodes (LEDs) was awarded the Nobel Prize in Physics. Subsequently, the United Nations declared the year of 2015 the International Year of Light and Light-based Technologies. [Third Place 2015 After Image photo contest.] —Herminso Villarraga-Gómez, Nikon Metrology Americas & University of North Carolina at Charlotte U.S.A.

Soliton amplification

Soliton amplification to 2 MW peak power in a high power, Er fiber amplifier, pumped by a Raman fiber laser. I like this image as it shows a variety of optical phenomenon. Scatter from the 975 nm pump lasers, and 1 um Yb fiber laser in the background are picked up by the camera's silicon sensor. The typical blue and green upconversion from Yb and Er fibers is also visible. Finally, nonlinearity from the intense soliton generates a deep green, and then red light, at the amplifier output. [Honorable Mention 2015 After Image photo contest.]—Jeffrey W. Nicholson, OFS

Light scattering in soap bubbles

Parhelic-like circle obtained with light scattering in soap bubbles. We have done a connection of this light pattern with the atmospheric optical phenomena known as parhelic circle, sun pillars and sun dogs. These phenomena are so interesting that, when they were observed in the sky of Rome in 1629, they led René Descartes stop thinking about Philosophy and turn his intellectual enthusiasm on the subject of Optics.[Honorable Mention 2015 After Image photo contest.]—Alberto Tufaile, University of São Paulo

Laser light diffracting in a cone

A direct image of the bare fiber tip, output port of the ytterbium femtosecond fiber laser of my construction. The laser light diffracting in a cone from a fiber tip is at 1,030 nm  wavelength, and it is directly shot by the DSLR camera. —Radosław Chrapkiewicz, Optics Division, Faculty of Physics, University of Warsaw, Poland

3-dimensional nested ring of light

This beautiful 3-dimensional nested ring of light was produced experimentally by placing a large glass capillary in front of a glowing heating element with an angular offset to excite skew rays that follow a helical path around the capillary axis.—George Y. Chen, University of South Australia

International Year of Light 2015 logo

International Year of Light 2015 logo was fabricated in fused silica glass volume by inducing birefringent nanorgatings using femtosecond laser. Different colors present different retardance induced. Photo taken in cross polarized light.—Titas Gertus, Workshop of Photonics (Altechna R&D)
