The Hatano–Nelson model with asymmetric couplings is demonstrated for the first time in phase locked laser arrays. The arrays exhibit steerable non-Hermitian skin effects.

Topological insulator lasers offer robustness and efficiency due to their unique properties but usually require cryogenic temperatures or optical pumping. Here the authors demonstrate an electrically pumped topological insulator laser operating at ro

The collective response of a system is profoundly shaped by the interaction dynamics between its constituent elements. In physics, tailoring these interactions can enable the observation of unusual phenomena that are otherwise inaccessible in standar

The ability to tailor the hopping interactions between the constituent elements of a physical system could enable the observation of unusual phenomena that are otherwise inaccessible in standard settings1,2. In this regard, a number of recent theoret

Cavities play a fundamental role in optical physics by providing spatio-temporal confinement of energy that facilitates light-matter interactions. They are routinely utilized in a variety of settings, ranging from lasers to spectral filters, to nonli

We report on the first realization of the Hatano-Nelson model in photonics by using an array of active unidirectional resonators that exhibit asymmetric nearest neighbor couplings. Non-Hermitian skin effect and laser phase locking is observed.

Topological insulator lasers (TILs) are a recently introduced family of lasing arrays in which phase locking is achieved through synthetic gauge fields. These single frequency light source arrays operate in the spatially extended edge modes of topolo

We report on the first observation of a gain-induced topological response in a photonic lattice exhibiting asymmetric long-range interactions enabled by unidirectional microrings under pumping. This new platform is used to implement the Haldane latti

We present a new class of topological cavities based on Majorana bound states. These cavities are inherently single-moded and robust to local disorder regardless of the size of the structure.
