Overcoming noise-agility trade-off in integrated lasers for precision sensing
Di Yu, Yitian Tong, Yu Xia +16
Lasers that combine narrow linewidths with rapid tunability are critical for applications such as coherent optical ranging, distributed fiber-optic sensing, and precision spectrosc…
Building reliable 3D photonic integrated circuits and cavities at the wafer scale
Yuhao Huang, Yunqi Fu, Yu Xia +6
Three-dimensional (3D) photonic integrated circuits (PIC) are emerging as an indispensable scheme for high density and multifunctional photonic systems. However, the wafer-scale sc…
Meter-long broadband chirped Bragg gratings for on-chip dispersion control and pulse shaping
Zhaoting Geng, Yitian Tong, Chuchen Zhang +12
Precise on-chip dispersion control is essential for advanced integrated photonic technologies, enabling applications ranging from high-speed communications and sensing to signal pr…
Design of Partially Etched GaP-OI Microresonators for Two-Color Kerr Soliton Generation at NIR and MIR
Houling Ji, Zhaoting Geng, Weiren Cheng +4
We present and theoretically investigate a dispersion engineered GaP-OI microresonator containing a partially-etched gap of 250 nm x 410 nm in a 600 nm x 2990 nm waveguide. This ga…
