Extended SSH Model in Non-Hermitian Waveguides with Alternating Real and Imaginary Couplings
We studied the topological properties of an extended Su–Schrieffer–Heeger (SSH) model composed of a binary waveguide array with alternating real and imaginary couplings. The topological invariant of the periodic structures remained quantized with chiral symmetry even though the system was non-Hermit...
