Topological -root Su-Schrieffer-Heeger model in a non-Hermitian photonic ring system
David Viedma, Anselmo M. Marques, Ricardo G. Dias +1
Square-root topology is one of the newest additions to the ever expanding field of topological insulators (TIs). It characterizes systems that relate to their parent TI through the…
Mode pumping in photonic lattices using a single tailored auxiliary waveguide
David Viedma, Jordi Mompart, Verònica Ahufinger
In this work, we propose a completely general method to pump the gapped topological modes of a lattice of optical waveguides by controlling the propagation constant of an auxiliary…
High Efficiency Topological Pumping with Discrete Supersymmetry Transformations
David Viedma, Gerard Queraltó, Jordi Mompart +1
Making use of the isospectrality of Supersymmetry transformations, we propose a general and high-fidelity method to prepare gapped topological modes in discrete systems from a sing…
Supersymmetry-enhanced Stark-Chirped Rapid-Adiabatic-Passage in multimode optical waveguides
David Viedma, Verònica Ahufinger, Jordi Mompart
We propose a method to efficiently pump an excited mode of a multimode optical waveguide starting from a fundamental-mode input by combining Stark-Chirped Rapid Adiabatic Passage (…
