Frequency combs—on-chip integration on track

EPFL scientists have found a way to miniaturize frequency combs, realizing a new step toward miniaturization of such tools. Their device can measure light oscillations with a precision of 12 digits.

Quasi noise-free digital holography

Noise originating from the coherent nature of laser light is the scourge of digital holography, reducing the quality of holographic images below that of conventional photographs. Now, Pasquale Memmolo of ISASI-CNR and collaborators ...

World's thinnest lens to revolutionize cameras

Scientists have created the world's thinnest lens, one two-thousandth the thickness of a human hair, opening the door to flexible computer displays and a revolution in miniature cameras.

Photoshop filters for safer bridges (w/ Video)

How can we constantly monitor the stability of a bridge or detect a leak in a gas pipeline in real time? A method based on optical fibers has become the norm in recent years. By carefully measuring the path of light in fibers ...
