Hollow Core Photonic Bandgap Fibers
Photonic Crystal & Multicore Fibers
Overview
Optical signal in a hollow core photonic bandgap fiber is guided in an air core surrounded by a high air filling factor PBG microstructured region (>90%). Added to the low bend sensitivity due to the core high NA, this confers to this fiber design significantly reduced material nonlinearities since more than 95% of optical power is propagating in air.
In addition air/undoped silica provides excellent temperature immunity critical for high performance fiber sensing and metrology applications.
