Market Overview

Optical fibers are used in a wide range of industries as a conduit to transmit light. Fibers comprising silicon offer a marriage of fiber optics with silicon photonics and opens the door to numerous opportunities in chemical sensing, thermal imaging, and related applications where infared light is used.

Applications:

Medical Applications: imaging and remote sensing Defense and Security: infrared light sources and thermal imaging

Technical Summary:

The Clemson technology is a type of optical fibers that incorporates an oxide glass cladding and crystalline silicon core. Oxide impurities that have been inadvertently introduced into the fiber core during drawing are eliminated by a chemical reaction from a scavenger prior to drawing resulting in lower loss and greater crystalline perfection.

Advantages:

• New fabrication method results in a fiber that combines lower losses with smaller cores, making the technology suitable for infrared nonlinear optics
• Provides greater transparency and efficiencies compared to current semiconductor technology due to the use of scavengers to eliminate the oxide scattering centers
• Resulting fibers are mechanically strong and are fabricated using well-established silicon manufacturing processes, which reduces costs while increasing yield
