Low-power, high-performance optical receivers

Thanks to IBM scientists, replacing copper wires with light to transfer data at improved speeds and with optimal energy efficiency is within reach.

Graphene offers protection from intense laser pulses

Researchers from Singapore and the UK have jointly announced a new benchmark in broadband, non-linear optical-limiting behavior using single-sheet graphene dispersions in a variety of heavy-atom solvents and film matrices.

Self-assembly and chains of rotating magnetic particles

Dr. Park and colleagues report on a new biosensing protocol based on monitoring changes in optical transmittance of a solution containing self-assembled chains of functionalized magnetic beads being rotated by an external ...
