In nature, there exist structures that are mirror images of each other but cannot be perfectly superimposed. These are known as chiral objects, derived from the Greek word for "hand," since left and ...

A new method of distinguishing chiral molecules could eventually detect distortions inside quantum and soft materials, find ...

Biophotonics is a multidisciplinary field that involves the development and application of light-based technologies to study, ...

Researchers report a nonvolatile phase-programmable spintronic terahertz emitter that uses femtosecond laser pulses to switch THz phase states and magnetic fields to reset them. The device enables ...

The difficulty stems from a fundamental tradeoff when performing THz measurements: achieving high spectral resolution versus high spatial resolution. To accurately capture the narrow spectral ...

Diagram of the electromagnetic spectrum, with visible spectrum and light highlighted separately. The full range of electromagnetic radiation, organized by frequency in Hertz and wavelength in meter.

Terahertz (THz) radiation, which occupies the frequency band between microwaves and infrared light, is essential in many next-generation applications, including high-speed wireless communications, ...

Scientists at the University of Warwick and University of Exeter have developed a fully fiber-coupled terahertz (THz) imaging system that significantly improves the speed, resolution, and clinical ...

Researchers summarize the recent developments and future research directions toward the broader implementation of terahertz ...
