By tailoring the spatial refractive index distribution to eliminate mode competitions and instabilities caused by the spatial hole burning effect, unidirectional power flow and single mode lasing can be achieved through our complex optics applications.

Extending the case to the microlaser array of 1D Su-Schrieffer-Heeger(SSH) model, the robust single mode is pinned at zero energy due to charge-conjugation symmetry, even with intentionally introduced perturbations. Optical setups with Monochromator and Lock-in Amplifiers are used to gather emission evolution from photoluminescence to amplified spontaneous emission and finally, to lasing. Further characterizations, such as polarization, OAM charge, and robust lasing with perturbation, are also done to prove the theoretical prediction.
