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. ...
For both cases in Fig. 2 , the input cores are the same graded-index core, which has been shown to be more advantageous during tapering than step-index core [10]. ...
