Low-loss integrated nanophotonic circuits with layered semiconductor materials
Tianyi Liu, Ioannis Paradisanos, Jijun He +13
Monolayer transition metal dichalcogenides with direct bandgaps are emerging candidates for microelectronics, nano-photonics, and optoelectronics. Transferred onto photonic integra…
High-yield wafer-scale fabrication of ultralow-loss, dispersion-engineered silicon nitride photonic circuits
Junqiu Liu, Guanhao Huang, Rui Ning Wang +5
Low-loss photonic integrated circuits (PIC) and microresonators have enabled novel applications ranging from narrow-linewidth lasers, microwave photonics, to chip-scale optical fre…
Monolithic piezoelectric control of soliton microcombs
Junqiu Liu, Hao Tian, Erwan Lucas +9
High-speed laser frequency actuation is critical in all applications employing lasers and frequency combs, and is prerequisite for phase locking, frequency stabilization and stabil…
Integrated turnkey soliton microcombs operated at CMOS frequencies
Boqiang Shen, Lin Chang, Junqiu Liu +14
While soliton microcombs offer the potential for integration of powerful frequency metrology and precision spectroscopy systems, their operation requires complex startup and feedba…
