Summary:
Iowa State University and Ames Laboratory researchers have developed new method for dispersion compensation in telecommunication systems using metamaterials.

Development Stage:
A proof-of-concept a dispersion-compensation system using phase-engineered metamaterials has been demonstrated experimentally, and ISU is seeking partners interested in commercializing this technology.

Description:
Dispersion management is a critical part of optical communication systems since the accumulation of dispersive effects due to propagation in a glass fiber results in limits on the distance data can travel as well as the rate of data transfer.  Approaches for dispersion compensation include the use of specialty fibers, which can require long lengths, and Bragg gratings, which can suffer from insertion loss.  To address the need for improved strategies for dispersion management, ISU and Ames Laboratory researchers have developed a new method for dispersion compensation using metamaterials that exhibit electromagnetically induced transparency.  This approach counteracts group velocity dispersion without the need for specialty fiber or Bragg gratings.  In addition, these phase-engineered materials are customizable and compact.

Advantage:
• Eliminates the need for Bragg gratings
• Eliminates the need for long pieces of specialty fiber optic cable
• Offers customizability and a small footprint
Application:
Telecommunications
