Abstract

A Mach-Zehnder and Michelson Hybrid (M²) interferometer is promoted to measure backreflection of modes at the hollow-core photonic bandgap fiber (HC-PBF) terminations. The results show that compared to the incident light intensity into the HC-PBF, the modes reflectivity is less than -80 dB at the flat termination, and it is about -90 dB for the fundamental modes.
