Polaritonic chemistry, which manipulates chemical and material properties using hybrid light–matter states formed by placing reactants in a vibration-tuned Fabry–Pérot (FP) cavity, has attracted ...

Nowadays, the dark of night is interspersed with the light of stars. But before the stars were born, did light shine at the beginning of the universe? The short answer is "no." ...

By extending the scope of the key insight behind Fermat’s Last Theorem, four mathematicians have made great strides toward building a “grand unified theory” of math.

Remarkably, despite the speckled and randomly fluctuating nature of the instantaneous electric field in incoherent light, those incoherent knots exhibit robust and stable topological configurations.

A tunable air-gap Fabry–Pérot filter consisting of distributed Bragg reflectors as cavity mirrors was developed to operate in the visible wavelength range. The wavelength tunability of the filter was ...

Miniaturized complementary metal-oxide semiconductor (CMOS) hyperspectral cameras utilizing Fabry–Perot interferometers (FPIs) have emerged as a low-cost solution providing fast-acquisition ...

A Fabry-Perot (F-P) based phase demodulation of heterodyne light-induced thermoelastic spectroscopy (H-LITES) is demonstrated. The vibration of quartz tuning fork (QTF) was detected by using F-P ...

Etalons are widely used in telecommunications, lasers, and spectroscopy to control and measure the wavelengths of light. Recent advances in fabrication techniques, developed by Optical Surfaces Ltd, ...

Phonon polaritons (PhPs) offer extreme confinement of optical fields and strong dispersion in the mid-infrared spectral region. To study the propagation and interference of PhPs in a 1-D system, we ...

A technique called plasmonic interferometry helps to detect spatial coherence in 'incoherent' light.
