Topologically Protected Parametric Wavelength Conversion in a Valley Hall Insulator (Laser Photonics Rev. 18(9)/2024)
Topological Photonic Valley Hall Insulator Using a Kagome System
A pump and a signal propagate through a topological photonic valley Hall insulator. The design by Dawn T. H. Tan and co-workers (see article number 2400045) utilizes a Kagome system with a honeycomb unit cell with three circular holes. Topological protection enables backscatter-free parametric wavelength conversion through 120-degree bends, with conversion efficiencies of up to −12 dB demonstrated. The authors further observe 7 dB slow light enhancement near the red edge in the boundary state's transmission band as well as Kerr-induced delocalization of the topological mode.
