Microscopic glass blowing used to make tiny optical lenses

Inserting air into hot glass to form a bubble has been used to make glass objects since Roman times. In new work, researchers apply these same glass blowing principles on a microscopic scale to make specialized miniature ...

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.

High power laser sources at exotic wavelengths

High power laser sources at exotic wavelengths may be a step closer as researchers in China report a fibre optic parametric oscillator with record breaking efficiency. The research team believe this could lead to new light ...

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 ...
