A new coating for glass developed by Rice University researchers and collaborators could help reduce energy bills, especially ...

By the mid 1970s, optical-communications systems were able to exploit the low losses of fibres at infrared wavelengths, which were below 0.47 dB/km for light at 1250 nm. An even lower-loss window was ...

The new ultralow loss optical microresonators can be finely tuned by simply rotating two intersecting optical fibers. Unlike current monolithic microresonators, these devices have a widely tunable ...

Knight Optical – the leading supplier of on-spec, metrology-tested optical components – has a wide-ranging portfolio of UV Fused Silica optics available from stock or as made-to-order components..

However, challenges such as precision fabrication and optical loss have hindered the confinement of optical fields to sub-10 nanometer (nm) or even 1-nm levels. But now, ...

A new class of ultralow loss optical microresonators formed at the intersection of two optical fibers enables precise, wide-range tuning of the free spectral range (FSR) by simple fiber rotation.
