MIT Develops Ferroelectric-graphene-based Waveguides

Researchers at MIT have developed a prototype device uses graphene sandwiched between two layers of a ferroelectric material to make simple, switchable plasmonic waveguides.

Light can be confined in these waveguides down to one part in a few hundreds of the free-space wavelength, representing an order-of-magnitude improvement comparable waveguide systems.

Practical applications could include optical interconnects and photonic integrated circuits.
