Quantum Dots Hit Telecom Band

LondonResearchers hit 1.55 micrometres, the exact wavelength fibre-optic networks run on.

Erbium-doped quantum dots assembled via hydrogen bonding cut light leakage, reaching 10 times the efficiency of disordered versions, researchers report.

The design offers a silicon-compatible path toward cheaper on-chip optical interconnects for data centers.
