NONLINEAR PLASMONICS

Ultrafast low-energy all-optical switching

Nature Photonics volume 14, pages 4–6 (2020)Cite this article

Subjects

The realization of ultrafast integrated opto-optical switches with ultra-low switching energies remains an ongoing challenge. Broadband, silicon-compatible devices relying on gap plasmons and saturable absorption in graphene could pave the way forward.
