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…
Observation of SQUID-like behavior in fiber laser with intra-cavity epsilon-near-zero effect
Jiaye Wu, Xuanyi Liu, Boris A. Malomed +10
Establishing relations between fundamental effects in far-flung areas of physics is a subject of great interest in the current research. We here report realization of a novel photo…
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…
Near perfect two-photon interference out a down-converter on a silicon photonic chip
Romain Dalidet, Florent Mazeas, Edgars Nitiss +5
Integrated entangled photon-pair sources are key elements for enabling large-scale quantum photonic solutions, and addresses the challenges of both scaling-up and stability. Here w…
