Low half-wave-voltage, ultra-high bandwidth thin-film LiNbO3 modulator based on hybrid waveguide and periodic capacitively loaded electrodes
Xuecheng Liu, Bing Xiong, Changzheng Sun +7
A novel thin-film LiNbO3 (TFLN) electro-optic modulator is proposed and demonstrated. LiNbO3-silica hybrid waveguide is adopted to maintain low optical loss for an electrode spacin…
Soliton dynamics in microresonators with XPM induced negative thermo-optic effect
Yanzhen Zheng, Changzheng Sun, Bing Xiong +10
Optical frequency comb generation in microresonators has attracted significant attention over the past decade, as it offers the promising potential for chip-scale optical frequency…
Integrated Gallium Nitride Nonlinear Photonics
Yanzhen Zheng, Changzheng Sun, Bing Xiong +7
Gallium nitride (GaN) as a wide-band gap material has been widely used in solid-state lighting. Thanks to its high nonlinearity and high refractive index contrast, GaN-on-insulator…
Electrically Pumped Orbital Angular Momentum (OAM) Laser at Telecom Wavelengths
Juan Zhang, Changzheng Sun, Bing Xiong +13
Semiconductor lasers capable of generating a vortex beam with a specific orbital angular momentum (OAM) order are highly attractive for applications ranging from nanoparticle manip…
