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…
Ultra-efficient frequency comb generation in AlGaAs-on-insulator microresonators
Lin Chang, Weiqiang Xie, Haowen Shu +13
Recent advances in nonlinear optics have revolutionized the area of integrated photonics, providing on-chip solutions to a wide range of new applications. Currently, the state of t…
On-chip polarization rotator for type I second harmonic generation
Eric J. Stanton, Lin Chang, Weiqiang Xie +12
We demonstrate a polarization rotator integrated at the output of a GaAs waveguide producing type I second harmonic generation (SHG). Form-birefringent phase matching between the p…
Dense III-V/Si Phase-Shifter Based Optical Phased Array
Weiqiang Xie, Tin Komljenovic, Jinxi Huang +2
High-performance integrated optical phased arrays (OPAs) are crucial for building up energy-efficient solid-state beam steering systems on a chip. This work demonstrates a first he…
On-Chip Integrated Quantum-Dot Silicon-Nitride Microdisk Lasers
Weiqiang Xie, Thilo Stöferle, Gabriele Rainò +8
Hybrid SiN-QD microlasers coupled to a passive SiN output waveguide with 7μm diameter and record low threshold density of 27 μJ cm-2 are demonstrated. A new design and unique proce…
