More light for medicine

PET scan, CT and MRI are almost standard in today's diagnostics – highly developed and very sophisticated. Although more capable and less cost-intensive, laser-optical diagnosis methods are, up to now, far less prevalent. ...

Millimeter-scale chip-based supercontinuum generation

In optics, when a collection of nonlinear processes act together on a pump beam, the resulting spectral broadening of the original pump beam gives rise to a supercontinuum. Supercontinuum sources for optical coherence tomography ...

Precise molecular fingerprinting on the fly

Electro-optic modulators, which can switch light on and off within just picoseconds, are enabling ever faster telecommunication over optical glass fibres, so that large movies can be streamed more smoothly across oceans into ...

A sharper look at the interior of semiconductors

Images provide information—what we can observe with our own eyes enables us to understand. Constantly expanding the field of perception into dimensions that are initially hidden from the naked eye, drives science forward. ...

Vision changes in space

Understanding the effects of microgravity on the human body is essential in enabling astronauts to travel through the harsh environment of space for months, or even years. Significant changes to the body's skeletal and muscle ...

Nanometer-scale growth of cone cells tracked in living human eye

Humans see color thanks to cone cells, specialized light-sensing neurons located in the retina along the inner surface of the eyeball. The actual light-sensing section of these cells is called the outer segment, which is ...
