Abstract

Spatially and spectrally resolved imaging (S2 imaging) and correlation filter technique (CFT) are two very different, widespread fiber mode analysis techniques. Both techniques have been successfully employed to decompose few-modes and multimode beams respectively. In this study, we present a novel experimental tool combining S2 imaging and CFT mode analyses in a unique system. We demonstrate that both methods are complementary with the ability to fully resolve scalar and vector-valued transverse modal fields. Using results from the combined experiment, mode powers (o2) evaluated from CFT analysis and S2 imaging are directly compared for a wide range of fiber beams (from single-to multi-mode). As a result, we experimentally identify the mode detection limit of each mode analysis and prove that S 2 imaging accuracy range can be considerably increased employing an analytical mode evaluation method. The conclusion contains a table summarizing the expertise of each mode analysis. © 1983-2012 IEEE.
