| Summary:
Over the past decade, cavity solitons have attracted substantial attention
for their rich dynamics and their myriad potential applications. Recently,
there has been growing interest in understanding cavity solitons in systems of
coupled resonators, where both new physics and applications can emerge. While
numerous works have theoretically studied the interplay between cavity solitons
and lattice topology, experimental demonstrations of cavity solitons in
topological lattices remain elusive. Here, we experimentally realize cavity
solitons in a Su-Schrieffer-Heeger (SSH) lattice and illustrate that the
synergy between topology and soliton formation dynamics can induce soliton
formation at the boundaries of a topological SSH lattice. Our work illustrates
the rich physics of cavity solitons in topological lattices and demonstrates a
flexible approach to study solitons in large-scale coupled resonator arrays.
