Non-Hermitian mode locking in an L-band monolithic InP dual-ring laser
Xiao Sun, Mohanad Al Rubaiee, Jue Wang +4
Coupling between laser cavities provides a means of controlling optical modes through their gain, loss, and hybridization. Here we demonstrate electrically controlled mode locking…
Heterogeneous-free narrow linewidth semiconductor laser with optical injection locking
Xiao Sun, Zhibo Li, Yiming Sun +6
Narrow linewidth lasers are indispensable for coherent optical systems, including communications, metrology, and sensing. Although compact semiconductor lasers with narrow linewidt…
Multi-Wavelength DFB Laser Based on Sidewall Third Order Four Phase-Shifted Sampled Bragg Grating with Uniform Wavelength Spacing
Xiao Sun, Zhibo Li, Yizhe Fan +5
We present the first demonstration of a 1550 nm multi-wavelength distributed feedback (MW-DFB) laser employing a third-order, four-phase-shifted sampled sidewall grating. By utiliz…
Narrow Linewidth Laser Based on Extended Topological Interface States in One-Dimensional Photonic Crystals
Xiao Sun, Zhibo Li, Yiming Sun +7
Recent advances in topological one-dimensional photonic crystal concepts have enabled the development of robust light-emitting devices by incorporating a topological interface stat…
