Mid- and far-infrared birefringent crystals are key functional materials for polarization control, laser technologies, and ...

The material the team studied, barium titanium sulfide (BaTiS 3), a hexagonal crystal, was already known to have large optical anisotropy, but scientists couldn't figure out why. It took years of back ...

In general, when you measure material properties such as optical permittivity, your measurement doesn’t depend on the direction in which you make it. However, recent research has shown that this is ...

Nonlinear optical crystals are at the forefront of advanced photonic technologies, enabling efficient frequency conversion and modulation of light by utilising intense electric fields to alter their ...

Nonlinear optical processes and their anisotropy are foundational to advanced optics, directly governing the function and efficiency of on-chip photonics and nano-optical devices. With integrated ...

The study of polymer fibres has increasingly benefited from the confluence of optical and mechanical characterisation techniques, which are pivotal in understanding both the microstructural and ...

Superconductors are materials which conduct electricity without any resistance when cooled down below a critical temperature. These materials have transformative applications in various fields, ...

Nanoscale maze-like magnetic patterns form reliably across strained substrates, removing a key bottleneck for faster, more efficient data-center optical links. (Nanowerk News) A collaborative team has ...
