Mid-infrared nanophotonics

Probing hyperbolic polaritons

Nature Photonics volume 9, pages 638640 (2015) | Download Citation

Hyperbolic phonon polaritons confined to the subdiffraction limit exhibit encouragingly long lifetimes and group velocities as slow as 0.002c. Researchers use a time-resolved set-up sensitive to nanometre-scale optical fields to shed light on the exciting optical properties of hyperbolic materials.
