On-chip quadratically nonlinear photodetector
Yu Zhang, Xiaoqing Chen, Mingwen Zhang +5
Involving deterministically nonlinear photoresponse in on-chip photodetector is intriguing to develop sophisticated functions in photonic integrated circuits, such as in-sensor com…
Giant Enhancement of Nonlinear Harmonic Generation in a Silicon Topological Photonic Crystal Nanocavity Chain
Qingchen Yuan, Linpeng Gu, Liang Fang +3
Strongly enhanced third-harmonic generation (THG) by the topological localization of an edge mode in a Su-Schrieffer-Heeger (SSH) chain of silicon photonic crystal nanocavities is…
A topological photonic ring-resonator for on-chip channel filters
Linpeng Gu, Qingchen Yuan, Qiang Zhao +5
A topologically protected ring-resonator formed in valley photonic crystals is proposed and fabricated on a silicon slab. The unidirectional transmission and robustness against str…
Fano resonance lineshapes in a waveguide-microring structure enabled by an air-hole
Linpeng Gu, Liang Fang, Hanlin Fang +5
We propose and demonstrate, by simply inserting an air-hole in the waveguide side-coupling with a microring resonator (MRR), the transmission spectrum presents Fano lineshapes at a…
Second harmonic and sum-frequency generations from a silicon metasurface integrated with a two-dimensional material
Qingchen Yuan, Liang Fang, Hanlin Fang +5
Silicon-based nonlinear metasurfaces were implemented only with third-order nonlinearity due to the crystal centrosymmetry and the efficiencies are considerably low, which hinders…
A compact structure for realizing Lorentzian, Fano and EIT resonance lineshapes in a microring resonator
Linpeng Gu, Hanlin Fang, Juntao Li +4
Microring resonators, as a fundamental building block of photonic integrated circuits, have been well developed into numerous functional devices, whose performances are strongly de…
