All-optical data processing via coherent control of metamaterial absorption
All-optical data processing via coherent control of metamaterial absorption
With internet traffic continuing to grow rapidly, there is continued, indeed increasing interest in new materials and new mechanisms for routing/switching optical signals, which can help to deliver the anticipated speed and capacity demands of next-generation data networks. Engaging the coherent interaction of optical waves on photonic metamaterial nanostructures provides for ultrafast all-optical control, at arbitrarily low intensity, of a wide variety of optical phenomena, from absorption and refraction to optical activity and anisotropy. We introduce this new coherent control concept and demonstrate ultrafast all-optical modulation that is well-suited for implementation in emerging coherent networks. We show that coherent control of absorption in a metamaterial nanostructure of sub-wavelength thickness offers all-optical control of near-infrared signals with THz modulation bandwidth.

Abstract
With internet traffic continuing to grow rapidly, there is continued, indeed increasing interest in new materials and new mechanisms for routing/switching optical signals, which can help to deliver the anticipated speed and capacity demands of next-generation data networks. Engaging the coherent interaction of optical waves on photonic metamaterial nanostructures provides for ultrafast all-optical control, at arbitrarily low intensity, of a wide variety of optical phenomena, from absorption and refraction to optical activity and anisotropy. We introduce this new coherent control concept and demonstrate ultrafast all-optical modulation that is well-suited for implementation in emerging coherent networks. We show that coherent control of absorption in a metamaterial nanostructure of sub-wavelength thickness offers all-optical control of near-infrared signals with THz modulation bandwidth.
