Optimized Fibers for Coupling Efficiency

NuBRIDGE fibers have small cores and high NAs resulting in small mode field diameters for excellent coupling efficiency to planar waveguides and silicon photonics devices.

The expected splice loss to standard single mode transmission fibers would be very high.

To address this issue NuBRIDGE fibers feature a proprietary core and clad composition that allows the core to thermally expand during splicing and still yield a very low splice loss.

Optical Benefits

  • Mode field diameter of UHNA fibers specified at three wavelengths to cover the widest range of applications.
  • Up to 500nm of operating range over a single fiber - ideal for WDM applications.


Mechanical Benefits

  • Exceptional coupling efficiency to planar waveguides, including silicon photonics chips.
  • Proprietary composition designed to thermally expand the core during splicing providing low splice loss to transmission fibers.
  • Low bend loss suitable for miniature devices.
