The sound of light: Photoacoustics for biomedical applications

Medical imaging techniques provide a unique view inside the body and are invaluable for diagnosis and disease monitoring. From X-ray, over MRI to ultrasound, the field is vast and diverse. When imaging biological tissue, ...

Creating frequency combs in microresonators

For the first time, scientists were able to create ultrashort dark and bright light pulses that are linked together in tiny glass rings called microresonators. Each of the flashes consist of many different, precisely defined ...

New compact terahertz laser with 120 frequencies

Researchers have taken a major step towards bringing terahertz frequencies out of their hard-to-reach region of the electromagnetic spectrum and into everyday applications. In a new paper, the researchers demonstrate a first-of-its-kind ...

A quantum view of 'combs' of light

Unlike the jumble of frequencies produced by the light that surrounds us in daily life, each frequency of light in a specialized light source known as a "soliton" frequency comb oscillates in unison, generating solitary pulses ...

Molecular device turns infrared into visible light

Light is an electromagnetic wave: It consists of oscillating electric and magnetic fields propagating through space. Every wave is characterized by its frequency, which refers to the number of oscillations per second, measured ...

The highest amplification in tiny nanoscale devices

A team of researchers from the University of Florida, led by Dr. Philip Feng, in collaboration with Prof. Steven Shaw in Florida Institute of Technology, has now demonstrated extremely high-efficient mechanical signal amplification ...

Novel design may boost efficiency of on-chip frequency combs

On the cover of the Pink Floyd album Dark Side of the Moon, a prism splits a ray of light into all the colors of the rainbow. This multicolored medley, which owes its emergence to the fact that light travels as a wave, is ...
