Nonlinear waveguide polaritons for long-distance propagation of spins at room temperature
Nature ·
The Brief
- Spintronics uses particle spin to transfer information, but propagation distances are short.
- Photons can carry spin over longer distances but lack the nonlinear interactions needed for processing.
- The research paper proposes nonlinear waveguide polaritons to propagate spins over long distances at room temperature.
Why it matters
It targets a known trade-off between spin-based information transfer range and the nonlinear interactions needed for control, a combination relevant to designing spin-based devices.
