3D Holographic Projection

The three-dimensional (3D) vectorial nature of electromagnetic waves of light has not only played a fundamental role in science but also driven disruptive applications in optical display, microscopy, and manipulation. However, conventional optical holography can address only the amplitude and phase information of an optical beam, leaving the 3D vectorial feature of light completely inaccessible. [..]

Computer Vision Technology

Will automated infection tracking become standard procedure in airports around the world? Real-time thermal monitoring combined with biometric data that could be immediately extracted and analyzed (using computer vision technology) would help airport personnel quickly identify individuals with potential illness in even the most crowded terminals. Possible points of contact with the individual could also [..]

Optical Transistors

Leading research groups in the field of nanophotonics are working toward developing optical transistors – key components for future optical computers. These photonic devices will process information with photons instead of electrons, thus reducing the heat and increasing the operation speed. However, photons do not interact with each other well, which creates a big problem [..]

Interferometer Sensor

Researchers are now developing a laser-based interferometer sensor that detects coronavirus at the earliest point of infection from a saliva or nasal swab in minutes. The scientists are developing a new rapid, noninvasive optical biosensor demonstrator that will detect COVID-19 in humans as soon as it is present in the body. With the ability to [..]

Diamond Raman Laser

Lasers that emit light at the sodium line (actually a doublet) at a wavelength of about 589 nm are used to produce artificial “guide stars” in the mesosphere at an altitude of around 90 km for use with adaptive optical (AO) systems integrated with large ground-based astronomical telescopes. These artificial stars allow astronomers to use [..]

Lung Tumors

People who are at high risk of developing lung cancer, such as heavy smokers, are routinely screened with computed tomography (CT), which can detect tumors in the lungs. However, this test has an extremely high rate of false positives, as it also picks up benign nodules in the lungs. Researchers have now developed a new [..]

Mid-Infrared Lasers

For the first time, researchers have fabricated high-performance mid-infrared laser diodes directly on microelectronics-compatible silicon substrates. The new lasers could enable the widespread development of low-cost sensors for real-time, accurate environmental sensing for applications such as air pollution monitoring, food safety analysis, and detecting leaks in pipes. Most optical chemical sensors are based on the [..]

Electronic Skin

As the environmental toll of plastic microparticles and nanoparticles has grown ever more apparent, the possible impact of plastic films in optoelectronic devices has started to raise concerns. A research team now offers one possible answer: Make the films out of fish scales. The team zeroed in on the transparent plastic films used in a [..]

Visible Light Communication

Vehicle-to-vehicle (V2V) positioning is an essential research for the security of autonomous vehicles. Due to low cost and easy accessibility, global positioning system (GPS) has been a popular solution. However, GPS has inadequate accuracy due to the signal blockage by buildings and multipath effect. Besides GPS, RADAR and LIDAR can achieve quite high accuracy, but [..]

Terahertz Waves

Terahertz waves are becoming ever more important in science and technology. They enable us to unravel the properties of future materials, test the quality of automotive paint and screen envelopes. But generating these waves is still a challenge. A team of researchers has now developed a germanium component that generates short terahertz pulses with an [..]

Luminous Clothing

Apart from AR and VR, there are recent developments in wearable technology.  A new approach to the design of light-emitting fabric could lead to the development of softer and more wearable luminous clothing, according to a project at the University of Windsor in Ontario. The fabrication of wearable e-textiles and smart clothing has until now [..]

Light Modulator

A team of researchers has described a method of designing metamolecules that incorporate two independently controllable subwavelength meta-atoms. This two-parametric control of the metamolecule secures the complete control of both amplitude and the phase of light – light modulator. A Korea Advanced Institute of Science and Technology (KAIST) research team in collaboration with the University [..]

Coronavirus Diagnosis

Recognizing that current methods of Coronavirus diagnosis take approximately one hour, a team of researchers has developed a method that combines optics and magnetic particles able to test 100 samples of patients potentially infected with the virus and reduce the diagnostic time to approximately 15 minutes. The time it currently takes for Coronavirus diagnosis poses [..]

Photonic Crystal

Researchers have seen light propagate in a special material without reflections. The material, a photonic crystal, consists of two parts that each have a slightly different pattern of perforations. Light can propagate along the boundary between these two parts in a special way: It is “topologically protected,” and therefore does not bounce back at imperfections. [..]

High-Tech Contact Lenses

Researchers have incorporated ultra-thin optical devices known as metasurfaces into off-the-shelf high-tech contact lenses to correct deuteranomaly, a form of red-green color blindness. The new customizable contact lens could offer a convenient and comfortable way to help people who experience various forms of color blindness. This research can also improve the quality of plastic opthalmic [..]

Photonics Technology

A recently released report from several German trade and research organizations argues that photonic technologies can represent “a driver of global sustainability,” and that the application of these technologies can prevent some 2.92 billion tons of annual CO2 emissions by 2030. Those avoided emissions, according to the study, would “correspond to at least 11% of [..]

Polarization Of Light

A team of physicists has found that a similarly asymmetrical pattern can be induced and measured at will in certain exotic materials, using a special kind of light beam (polarization of light) to stimulate the material. In this case, the phenomenon of “handedness,” known as chirality, occurs not in the structure of the molecules themselves, [..]
