μ-MOPA Architecture for Photonic Integrated Solid State Laser
Yu Guo, Yubo Wang, Haoqi Zhao +4
Diode-pumped solid-state (DPSS) lasers play a central role in modern photonics owing to their exceptional efficiency and ability to extend spectral coverage beyond the reach of sem…
Simultaneous Type-0 and Type-I Optical Parametric Oscillation in Submicron Poled Thin-Film Lithium Niobate
Fengyan Yang, Hong X. Tang
We demonstrate dual optical parametric oscillations in a thin-film lithium niobate microring resonator enabled by polarization-insensitive submicron periodic poling. Under degenera…
2D Optical Beam Scanning using Integrated Acousto-Optics and a Frequency Comb
Shucheng Fang, Qixuan Lin, Fengyan Yang +5
Optical beam steering is an essential technology for free-space optical communication, reconfigurable optical networks and quantum information systems. Yet conventional steering me…
Degeneracy-Locked Optical Parametric Oscillator
Fengyan Yang, Jiacheng Xie, Yiyu Zhou +4
Optical parametric oscillators (OPOs) are widely utilized in photonics as classical and quantum light sources. Conventional OPOs produce co-propagating signal and idler waves that…
Symmetric Second-Harmonic Generation in Sub-wavelength Periodically Poled Thin Film Lithium Niobate
Fengyan Yang, Juanjuan Lu, Mohan Shen +2
Second harmonic generation (SHG) extensively employs periodically poled nonlinear crystals through forward quasi-phase-matching to achieve efficient frequency conversion. As poling…
Autonomous frequency locking for zero-offset microcomb
Ming Li, Feng-Yan Yang, Juanjuan Lu +2
The stabilization of optical frequency comb conventionally relies on active electronic feedback loops and stable frequency references. Here, we propose a new approach for autonomou…
