A cantilever-based sub-λ3 mode-volume optical microcavity

Microcavities have been popular for a number of applications, ranging from micorlasers, cavity quantum electrodynamics studies and sensing. The enhanced coupling in the cavity is usually achieved via a high quality factor. This,...[more]


Classical entanglement: Speeding particles in the sights of a laser

A radially polarized laser beam acts as a motion sensor for fast particles It might be easier to track tiny particles in the future – even when they hurtle along with the speed of a rifle bullet. This is thanks to researchers...[more]


Photonic crystal fibre: a multi-purpose sensor

A flying microbead in a hollow glass fibre measures temperature, vibrations and electric fields with high spatial resolution. Glass fibres can do more than transport data. A special type of glass fibre can also be used as a...[more]


World-Record Deep-Ultraviolet to Mid-Infrared Supercontinuum Light Generated in Photonic Crystal Fibre

Bright light sources delivering continuous bands of wavelength from the ultraviolet (UV) to the infrared (IR) are of great importance in advanced optical microscopy, spectroscopy and many other fields. A proven approach to...[more]
