Furukawa Lab
Machine-translated · View original
A lab that explores how light propagates in polymer optical fibers and how they can detect strain.
AboutAbout the lab
Exploring light and strain with polymer optical fibers
The Furukawa Lab studies the materials of polymer optical fibers, which are made of polymers, and sensors that use them.
The lab works with fibers whose cores have suppressed birefringence, and investigates the relationship between core composition and the properties of light.
It also works on polymer optical fiber sensors that detect strain, and on materials that combine polymers with helical carbon microstructures.
Key terms
- Polymer optical fiber
- An optical fiber made of polymer rather than glass.
- Birefringence
- A property in which light travels through a material differently depending on its polarization direction.
- Carbon microcoil
- A tiny spring-like helical structure made of carbon.

*Illustrative imagePolymer Optical Fibers with Suppressed Birefringence
The lab studies polymer optical fibers whose cores have suppressed birefringence, the difference in how light propagates depending on its polarization direction. It also investigates how core composition affects the fiber's ability to preserve the polarization direction of light.
*Illustrative imageSensors That Detect Strain with Light
The lab studies polymer optical fiber sensors that detect strain. It analyzes the polymerization method used to make the fiber's base material (preform) and how light scatters inside the fiber.
*Illustrative imageAligning Carbon Microcoils
The lab studies how to align carbon microcoils, which are helical carbon microstructures, by using the orientation of the host polymer. It also works on methods for sorting coils by size, aimed at polymer composite materials that absorb electromagnetic waves.
