Scientific Reports, Published online: 05 June 2026; doi:10.1038/s41598-026-56158-5 Apodized fiber Bragg grating filters for efficient QKD channel separation in QKD-over-DWDM systems

Nature Communications, Published online: 07 May 2026; doi:10.1038/s41467-026-72129-w Single-photon real-time imaging reveals the polarization dynamics of spatial modes in few and multimode optical fibres, enabling mode-resolved polarimetry and visualization of complex fibre dynamics.

A new speed record has been set for data transmission through an existing, commercially installed fibre-optic cable, with 450 terabits per second – or 450,000,000,000,000 bits per second – being beamed through a pair of cables underneath London’s busy streets. Polina Bayvel at University College London and her colleagues achieved the record using existing fibre-optic cables running from their lab…

A new cool result showed up in Science this week, implying that we may be able to increase the information-carrying capacity of fiber optics beyond what had been thought of as (material-dependent) fundamental limits.  To appreciate this, it's good to think a bit about the way optical fiber carries information right now, including the bits of this blog post to you.  (This sort of thing is discusse…
