Paper Abstract

We have demonstrated for the first time lasing action in a Bound stae in the Continuum (BIC)-based cavity. We have achieved this result on a platform made of an ensemble of dielectric resonators that is compatible with electrical pumping. Lasing action was observed at room temperature in a compact array with a footprint as small as 9x9 μm2. The lasing wavelength follows the prediction of the BIC mode as the radius is varied for different array sizes thereby demonstrating the robustness and scalability of the system. Additionally, this work paves the way for future investigation into the intriguing topological properties of BICs. Furthermore, this design can be implemented for an electrically pumped equivalent thereby taking full advantage of its power-efficient performance. The fundamental principle of bound states can also be used to design in-plane emitting laser.
