Disorder-assisted real–momentum topological photonic crystal

Romain Christophe Rémy Fleury, Haoye Qin, Bo Li, Ji Zhou

Topological defects and disorder counteract each other. Intuitively, disorder is considered detrimental, requiring efforts to mitigate its effects in conventional topological photonics. We propose a counter-intuitive approach that exploits a real–momentum ...

Ultrabroadband milliwatt-level resonant frequency doubling on a chip

Camille Sophie Brès, Marco Clementi, Ji Zhou

Microresonators are powerful tools to enhance the efficiency of second-order nonlinear optical processes, such as second-harmonic generation, which can coherently bridge octave-spaced spectral bands. However, dispersion constraints such as phase-matching a ...

Self-organized spatiotemporal quasi-phase-matching in microresonators

Camille Sophie Brès, Jianqi Hu, Anton Stroganov, Edgars Nitiss, Ozan Yakar, Marco Clementi, Ji Zhou

Quasi-phase-matching (QPM) is a widely adopted technique for mitigating stringent momentum conservation in nonlinear optical processes such as second-harmonic generation (SHG). It effectively compensates for the phase velocity mismatch between optical harm ...
