Observation of Unidirectional s-p Orbital Topological Edge States in Driven Photonic Lattices
Gayathry Rajeevan, Sebabrata Mukherjee
Time-periodic modulation of a static system is a powerful method for realizing robust unidirectional topological states. So far, all such realizations have been based on interactio…
Phase and Photon Number Dependent NOON State Localization in Flat Band Lattices
Rishav Hui, Trideb Shit, Marco Di Liberto +2
Flat-band lattices supporting compact localized states provide a versatile platform for exploring unconventional transport phenomena in photonic, ultracold atomic, electronic, and…
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…
Probing the Topological Anderson Transition in Quasiperiodic Photonic Lattices via Chiral Displacement and Wavelength Tuning
Abhinav Sinha, Trideb Shit, Avinash Tetarwal +2
The interplay of topology and disorder in quantum dynamics has recently attracted significant attention across diverse platforms, including solid-state devices, ultracold atoms, an…
Nonlinear Switch and Spatial Lattice Solitons of Photonic s-p Orbitals
Gayathry Rajeevan, Sebabrata Mukherjee
We develop fs laser-fabricated asymmetric couplers and zig-zag arrays consisting of single and two-mode waveguides with bipartite nonlinearity. The fundamental mode ( orbital) i…
Optical control of topological end states via soliton formation in a 1D lattice
Christina Jörg, Marius Jürgensen, Sebabrata Mukherjee +1
Solitons are self-consistent solutions of the nonlinear Schrödinger equation that maintain their shape during propagation. Here we show, using a pump-probe technique, that soliton…
