A team of DARPA-funded researchers led by Honeywell International Inc. developed new hollow-core fiber is the first to include three critical performance-enabling properties:
* Single-spatial-mode: light can take only a single path, enabling higher bandwidth over longer distances;
* Low-loss: light maintains intensity over longer distances;
* Polarization control: the orientation of the light waves is fixed in the fiber, which is necessary for applications such as sensing, interferometry and secure communications.
Hollow-core fiber can also be bent and coiled while guiding light at speeds 30 percent faster than conventional fiber. The hollow fiber also will enable higher intensity optical beams.
The real breakthrough with COUGAR (Compact Ultra-Stable Gyro for Absolute Reference) fiber is that it can achieve a single-spatial-mode, maintain polarization and provide low loss, all while keeping more than 99 percent of the optical beam in the air.
