Dielectric‐Metasurface‐Enhanced Kerr Self‐Modulation for Passively Q‐Switching

Laser &Photonics Reviews, Volume 18, Issue 4, April 2024.
By exploiting the enhanced Kerr effect from a periodic array of silicon nanodisks, the Mie resonance of the unit cells enhances is redshifted, achieving a novel transmission modulation for pulsed laser generation. And a stable Q‐switched pulse laser output with a duration of 1.4 µs and a repetition rate of 60 kHz is achieved.
