State-recycling and time-resolved imaging in topological photonic lattices
Sebabrata Mukherjee, Harikumar K. Chandrasekharan, Patrik Öhberg +2
Photonic lattices - arrays of optical waveguides - are powerful platforms for simulating a range of phenomena, including topological phases. While probing dynamics is possible in t…
Observation of Ground and Excited Flat Band States in Graphene Photonic Ribbons
Camilo Cantillano, Sebabrata Mukherjee, Luis Morales-Inostroza +5
Understanding the wave transport and localisation is a major goal in the study of lattices of different nature. In general, inhibiting the energy transport on a perfectly periodic…
Observation of robust flat-band localization in driven photonic rhombic lattices
Sebabrata Mukherjee, Robert R. Thomson
We demonstrate that a flat-band state in a quasi-one-dimensional rhombic lattice is robust in the presence of external drivings along the lattice axis. The lattice was formed by pe…
Dissipatively Coupled Waveguide Networks for Coherent Diffusive Photonics
Sebabrata Mukherjee, Dmitri Mogilevtsev, Gregory Ya. Slepyan +3
A photonic circuit is generally described as a structure in which light propagates by unitary exchange and transfers reversibly between channels. In contrast, the term `diffusive'…
