Merging Metamaterials with Quantum Photonics
Over the past decade, one of the major focuses for the area of nanophotonics has been on
developing a new class of “plasmonic” structures and “metamaterials” as potential building
blocks for advanced optical technologies, including data processing, exchange and storage;
a new generation of cheap, enhanced-sensitivity sensors; nanoscale-resolution imaging
techniques; new concepts for energy conversion including improved solar cells, as well as
novel types of light sources. Designing plasmonic metamaterials with versatile properties
that can be tailored to fit almost any practical need promises a range of potential
breakthroughs. However, to enable these new technologies based on plasmonics, grand
limitations associated with the use of metals as constituent materials must be overcome.
In the structures demonstrated so far, too much light is absorbed in the metals (such as
silver and gold) commonly used in plasmonic metamaterials. The fabrication and integration
of metal nanostructures with existing semiconductor technology is challenging, and the
materials need to be more precisely tuned so that they possess the proper optical
properties to enable the required functionality. Our recent research aims at developing
new designs and plasmonic materials (other than the metals used so far) that will form the
basis for future low-loss, durable, CMOS-compatible devices that could enable full-scale
development of the plasmonic and metamaterial technologies. Can these recently developed
plasmonic structures and metamaterials based on new material platforms help in unfolding
the potential of quantum photonics? We report on our first efforts in that direction.
