Enhanced Silicon Optical Fiber

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.

 

Application                                                                                                   Stage of Development

Medical Applications: Imaging and remote sensing                                     Technology is mature 

Defense and Security: Infrared light sources and thermal imaging                         

 

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

 

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.
