Self-organized spatiotemporal quasi-phase-matching in microresonators
Ji Zhou, Jianqi Hu, Marco Clementi +4
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…
Integrated Backward Second-Harmonic Generation Through Optically Induced Quasi-Phase Matching
Ozan Yakar, Edgars Nitiss, Jianqi Hu +1
Quasi-phase-matching for efficient backward second-harmonic generation (BSHG) requires sub-m poling periods, a non-trivial fabrication feat. For the first time, we report int…
Single-shot Kramers-Kronig complex orbital angular momentum spectrum retrieval
Zhongzheng Lin, Jianqi Hu, Yujie Chen +2
Orbital angular momentum (OAM) spectrum diagnosis is a fundamental building block for diverse OAM-based systems. Among others, the simple on-axis interferometric measurement can re…
Photo-induced cascaded harmonic and comb generation in silicon nitride microresonators
Jianqi Hu, Edgars Nitiss, Jijun He +5
Silicon nitride (SiN) is an ever-maturing integrated platform for nonlinear optics. Yet, due to the absence of second-order () nonlinearity, SiN is mostly…
Coherent Photogalvanic Effect for Second-Order Nonlinear Photonics
Ozan Yakar, Edgars Nitiss, Jianqi Hu +1
The coherent photogalvanic effect leads to the generation of a current under the absorption interference of coherent beams and allows for the inscription of space-charge gratings l…
Optically reconfigurable quasi-phase-matching in silicon nitride microresonators
Edgars Nitiss, Jianqi Hu, Anton Stroganov +1
Bringing efficient second-order nonlinear effects in integrated photonics is an important task motivated by the prospect of enabling all possible optical functionalities on chip. S…
Reconfigurable radiofrequency filters based on versatile soliton microcombs
Jianqi Hu, Jijun He, Junqiu Liu +5
The rapidly maturing integrated Kerr microcombs show significant potential for microwave photonics. Yet, state-of-the-art microcomb based radiofrequency (RF) filters have required…
