A research team has fabricated a subwavelength grating from an epitaxial molybdenum diselenide (MoSe2) layer roughly 42 nanometers thick and measured optical confinement consistent with a bound state ...

Mid-infrared wavelengths are called the molecular fingerprint region because it contains the fundamental vibrational modes inherent to the substances of interest. Since the mid-infrared spectrum can ...

Ultrafast pump-probe measurements in the water-window region require a coherent light source with a long driving wavelength and high pulse energy. The schematic diagram of the femtosecond laser system ...

Fibre optics is now the fastest and most reliable technology to deliver internet connection. Data is transmitted through fast-travelling pulses of light that bounce off the walls of the fibre cables ...
