Optoacoustic imaging powered by short bursts of continuous wave (CW) lasers can stimulate the emission of ultrasound waves inside an animal or in human subjects. The method can noninvasively capture blood flow and produce ...
Newton's third law dictates that forces between interacting particles are equal and opposite for closed systems. In a non-equilibrium environment, the third law can be defied, giving rise to "nonreciprocal" forces. Theoretically, ...
A KAIST research team developed a silicon optical phased array (OPA) chip, which can be a core component for three-dimensional image sensors. This research was co-led by Ph.D. candidate Seong-Hwan Kim and Dr. Jong-Bum You ...
Researchers have demonstrated that a laser can transmit an audible message to a person without any type of receiver equipment. The ability to send highly targeted audio signals over the air could be used to communicate across ...
A new way of rapidly identifying bacteria, which requires a slight modification to a simple microscope, may change the way doctors approach treatment for patients who develop potentially deadly infections and may also help ...
A new optical microscope system called stimulation and imaging-based functional optical microscopy (SIFOM) can stimulate multiple cells simultaneously via a holographic method and monitor cell activity after the stimulation ...
From almost instantaneous wireless transfer of huge amounts of data and easy detection of explosives, weapons, or harmful gases, to safe 3-D medical imaging and new advances in spectroscopy —technologies based on terahertz ...
A team at the University of Warsaw, Faculty of Physics has created a laser capable of generating ultrashort pulses of light even under extremely difficult external conditions. This unique combination of precision and resilience ...
A compact 'on-silicon-chip' laser has been developed by A*STAR researchers that boasts both excellent confinement of light for lasing and the ability to efficiently share the laser light with nearby components.
As the world's exponentially growing demand for digital data slows the Internet and cell phone communication, City College of New York researchers may have just figured out a new way to increase its speed.
