Ultrahigh-efficiency second-harmonic generation in nanophotonic PPLN waveguides
Cheng Wang, Carsten Langrock, Alireza Marandi +5
Periodically poled lithium niobate (PPLN) waveguide is a powerful platform for efficient wavelength conversion. Conventional PPLN converters however typically require long device l…
Electronically Programmable Photonic Molecule
Mian Zhang, Cheng Wang, Yaowen Hu +4
Physical systems with discrete energy levels are ubiquitous in nature and are fundamental building blocks of quantum technology. Realizing controllable artifcial atom- and molecule…
Monolithic photonic circuits for Kerr frequency comb generation, filtering and modulation
Cheng Wang, Mian Zhang, Rongrong Zhu +2
Microresonator Kerr frequency combs, which rely on third-order nonlinearity (), are of great interest for a wide range of applications including optical clocks, pulse shap…
Broadband electro-optic frequency comb generation in an integrated microring resonator
Mian Zhang, Brandon Buscaino, Cheng Wang +5
Optical frequency combs consist of equally spaced discrete optical frequency components and are essential tools for optical communications and for precision metrology, timing and s…
