Ultra-wideband electrically-tuned mid-infrared on-chip parametric oscillator
Alexander Y. Hwang, Hubert S. Stokowski, Luke Qi +7
Developing compact, broadband mid-infrared coherent sources for applications in spectroscopy and sensing remains a pressing challenge in photonics. However, material limitations an…
Low-power integrated optical parametric amplification via second-harmonic resonance
Devin J. Dean, Taewon Park, Hubert S. Stokowski +6
Optical amplifiers are fundamental to modern photonics, enabling long-distance communications, precision sensing, and quantum information processing. Erbium-doped amplifiers domina…
Low-loss, fabrication-tolerant, and highly-tunable Sagnac loop reflectors and Fabry-Pérot cavities on thin-film lithium niobate
Luke Qi, Ali Khalatpour, Jason Herrmann +8
We present low-loss () and power-efficient Mach-Zehnder interferometers (MZIs) on thin-film lithium niobate. To accurately measure low MZI losses, we develop a self-calibra…
Roughness-Limited Performance in Ultra-Low-Loss Lithium Niobate Cavities
Ali Khalatpour, Luke Qi, Martin M. Fejer +1
Achieving low optical loss is critical for scaling complex photonic systems. Thin-film lithium niobate (TFLN) offers strong electro-optic and nonlinear properties in a compact plat…
