A 10-mode photonic lantern with insertion losses ranging from 0.6 to 2.0 dB across all the modes and a record-low pairwise 4-dB mode-dependent loss at C-band was demonstrated.  ...  We propose a novel triple-clad photonic lanterns for mode scaling. This novel structure alleviates the adiabatic tapering requirement for the fabrication of large photonic lanterns.  ...  In this paper, we demonstrate PLs using novel triple-clad micro-structured preforms fabricated by drilling, which not only ease the fabrication complexity for mode scalablity but also alleviate the adiabatic  ...
