Diode effects are of great interest for both fundamental physics and modern technologies. Electrical diode effects (nonreciprocal transport) have been observed in Weyl systems. Optical diode effects arising from the Weyl fermions have been theoretically co ...

The Terahertz (THz) frequency domain lies between the realms of microwave and optics, with frequencies conventionally spanning the 0.1-10 THz spectral range [1]. Many commercially-available THz systems routinely exploits optical down/up conversion mechanis ...

Glass has been the material of choice for making optical elements, in large part due to its intrinsic properties: a temperature-dependent viscosity, which enables shaping the material into a broad variety of functional and artistic glassware. Silica glass ...

Ultraviolet (UV) pulses at 450 fs are a powerful tool for femtosecond laser waveguide writing in fused silica. Whereas typically sub-200 fs pulses at a high exposure dose were required, UV light efficiently creates waveguides with propagation losses below ...
