Nonlinearity-induced Band Gap Transmission in Dispersive and Flat Band Photonic Lattices
Avinash Tetarwal, Shailja Sharma, Sebabrata Mukherjee
Nonlinear interactions in photonic non-dispersive (flat) bands remain largely unexplored, despite their potential to yield exotic phenomena. Here, we demonstrate nonlinearity-induc…
