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…
Single-Mode Squeezed Light Generation and Tomography with an Integrated Optical Parametric Oscillator
Taewon Park, Hubert S. Stokowski, Vahid Ansari +9
Quantum optical technologies promise advances in sensing, computing, and communication. A key resource is squeezed light, where quantum noise is redistributed between optical quadr…
Integrated frequency-modulated optical parametric oscillator
Hubert S. Stokowski, Devin J. Dean, Alexander Y. Hwang +7
Optical frequency combs have revolutionized precision measurement, time-keeping, and molecular spectroscopy. A substantial effort has developed around "microcombs": integrating com…
Mid-infrared spectroscopy with a broadly tunable thin-film lithium niobate optical parametric oscillator
Alexander Y. Hwang, Hubert S. Stokowski, Taewon Park +7
Mid-infrared spectroscopy, an important and widespread technique for sensing molecules, has encountered barriers stemming from sources either limited in tuning range or excessively…
Integrated Quantum Optical Phase Sensor
Hubert S. Stokowski, Timothy P. McKenna, Taewon Park +6
The quantum noise of light fundamentally limits optical phase sensors. A semiclassical picture attributes this noise to the random arrival time of photons from a coherent light sou…
Ultra-broadband mid-infrared generation in dispersion-engineered thin-film lithium niobate
Jatadhari Mishra, Marc Jankowski, Alexander Y. Hwang +8
Thin-film lithium niobate (TFLN) is an emerging platform for compact, low-power nonlinear-optical devices, and has been used extensively for near-infrared frequency conversion. Rec…
High efficiency second harmonic generation of blue light on thin film lithium niobate
Taewon Park, Hubert S. Stokowski, Vahid Ansari +4
We demonstrate second harmonic generation of blue light on an integrated thin-film lithium niobate waveguide and observe a conversion efficiency of , si…
