Latest Patents

Zengkai Shao holds a patent for a "Topological bulk laser and method based on band inversion and reflection of optical field." This invention features a topological photonic crystal that exhibits energy band inversion between dipole and quadrupole modes near the center of the Brillouin zone. The design incorporates a trivial photonic crystal that does not have band inversion, allowing for effective splicing. The mechanism of reflection and confinement of the optical field occurs at the interface, forming a closed contour that creates a laser cavity. This innovative approach enables single-mode lasing with directional vertical emission, achieving low thresholds, narrow linewidths, and high side-mode suppression ratios at room temperature. The invention also reduces fabrication difficulties and costs while improving heat dissipation and electrical injection efficiency, ultimately enhancing the lifetime and stability of devices.
