A coherent perfect absorber is a system in which the complete absorption of electromagnetic radiation is achieved by controlling the interference of multiple incident waves. Here, we review recent ...
To build the antilaser, which Cao and colleagues call a “coherent perfect absorber,” the researchers split a beam from a titanium-sapphire laser in two. The laser emitted light in the infrared ...
The device, termed a “coherent perfect absorber,” functions as an absorptive interferometer, with potential practical applications in integrated optics. Last summer, Yale physicist A. Douglas Stone ...
Chong and co call their new devices coherent perfect absorbers or CPAs and a number of applications in communications spring to mind. They show that a single material can absorb perfectly at a ...
The device works by forming a standing wave from incident light waves, where interactions with an ultrathin absorber lead ... demonstration of broadband coherent perfect absorption in compact ...
The researchers built what they call a Coherent Perfect Absorber (CPA), a silicon wafer that traps and dissipates incoming coherent light of a predefined wavelength. In other words, just as a ...
They achieved a degeneracy of two coherent perfect absorbing modes ... Therefore, the system usually behaves as two perfect absorbers. But with an optimization of the coupling between the ...
This absorption-amplification method, which has just been published in the scientific journal Science under the title “Massively degenerate coherent perfect absorber for arbitrary wavefronts ...
Less than a year after it was first suggested, the world's first antilaser is here. A team of physicists have built a contraption that, instead of flashing bright beams, utterly extinguishes ...
