Summary

The same 1×7 lanterns collected visible light broadly and separated 1520–1610-nanometer bands by spatial route.

Heterogeneous bundles of SM450 and SMF28 cores break modal degeneracy without a rigid geometry. Experiments found broadband collection from 350 to 740 nanometers and passive spectral sorting in the H band, a potential route to feeding band-optimized astronomical spectrographs.

Why it matters

The same 1×7 lanterns collected visible light broadly and separated 1520–1610-nanometer bands by spatial route.
