IBM Researchers Build Multi-Layer Graphene for Photonics Applications

While new breakthroughs continue to come in using graphene (or cousins of graphene) for electronics applications, research in the area of using graphene for photonics applications is growing. The latest use of graphene for photonics comes from IBM where researchers have created a graphene/insulator superlattice capable of serving as a terahertz frequency notch filter and linear polarizer, according to an article in EE Times . IBM has certainly been a trailblazer in using graphene for electronics applications over the years, such as their graphene transistor work and then later an integrated circuit . But IBM—along with other researchers outside of Big Blue —has also been hard at work looking at how graphene could be used in optoelectronics . IBM Fellow Phaedon Avouris told EE Times that "In addition to its good electrical properties, graphene also has exceptional optical p...
