Customized fiber generates Bessel beams

An all fiber-based approach to generating special optical beams, called Bessel beams, could open up new applications in imaging, optical trapping and communications.

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 ...

Flattening the curve: Nano-film enhanced supercontinuum edition

Providing light with tailored properties through ultrafast supercontinuum generation represents an active field of nonlinear science research. A German-Australian research collaboration has presented a new concept that includes ...

Bright prospects for OCT retinal scans at 30

Around the world, every second, someone gets a retinal OCT scan, typically as a routine portion of an eye exam. The high-resolution images obtained by OCT allow ophthalmologists to diagnose and monitor treatment for many ...

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 ...
