There is a long-standing folk art in China called "rice carving," in which lifelike artistic patterns are carved on rice with a length of only about 5 mm. These works need to be appreciated with a magnifying glass.
A new publication from Opto-Electronic Advances discusses highly efficient vectorial field manipulation using a transmitted tri-layer metasurface.
While conventional photodetectors can only measure light intensity, the light field contains much richer information. This information includes but is not limited to phase, polarization, and spectrum.
Metamaterials and metaoptics offer a broad dimension to explore exotic functionalities in physics and optics. In a new report now published in Science Advances, Jie Peng and a team of scientists in physics and interdisciplinary ...
Polarization has been a central concept to our understanding of optics and has found many applications ranging from quantum science to our daily life. 3D polarization structures possess peculiar optical features and extra ...
Kerr microcombs are sets of equidistant spectral lines generated by pumping a high-Q microresonator with a resonant continuous-wave single-mode laser. They have arguably created a new field in cavity nonlinear photonics, ...
In research published today in Nano Letters, physicists have delivered an unexpected boost for researchers with a new technique for 3D nanoscale elemental analysis for ion-electron microscope systems that allows the scientific ...
The interaction of light with matter lies at the heart of processes in nature and in society. For example, in a solar cell, light is converted to an electrical current, but the efficiency of this conversion process can be ...
Researchers at LSU, in collaboration with Zuse Institute in Berlin, Germany, have developed an ultraviolet metasurface that discriminates between left- and right-handed amino acids with attomolar sensitivity.
As anyone who has recently tried out an augmented reality headset knows, the technology is not yet ready to be part of our everyday lives. Researchers have been working to perfect high-performing augmented reality (AR) glasses, ...
