Study Demonstrates a Special Equal-Inclination Interference Employing Non-Monochromatic Photons

Optical interference is not only a fundamental phenomenon that has enabled new theories of light to be derived, but it has also been used in interferometry for the measurement of small displacements, refractive index changes, and surface irregularities.

Meta-Optics with Waveguide Technologies Propels Photonic Integrated Circuits to New Heights

Comprised of judiciously engineered microscopic photonic structures with subwavelength features, the concept of metasurface and metamaterials have proven fruitful results in the realm of meta-optics. Previous research attentions are mainly devoted to applying meta-structures to tailor light in free space and develop relevant devices and applications.

Using Superconducting Materials to Create Invisibility Devices

Invisibility devices may soon no longer be the stuff of science fiction. A new study published in the De Gruyter journal Nanophotonics by lead authors Huanyang Chen at Xiamen University, China, and Qiaoliang Bao, suggests the use of the material Molybdenum Trioxide (a-MoO3) to replace expensive and difficult to produce metamaterials in the emerging technology of novel optical devices.
