Coupling light into a hollow-core fiber with mitigated excitation of higher-order modes

Coupling light into a hollow-core fiber with mitigated excitation of higher-order modes
Coupling light into a hollow-core fiber with mitigated excitation of higher-order modes

We show experimentally that unwanted crosscoupling into higher-order modes of a hollow-core fiber can be reduced to values close to -40 dB when optimizing the input beam size for their suppression rather than optimizing it for the minimum insertion loss.

Abstract

We show experimentally that unwanted crosscoupling into higher-order modes of a hollow-core fiber can be reduced to values close to -40 dB when optimizing the input beam size for their suppression rather than optimizing it for the minimum insertion loss.
