Practical Limits on Integrated Squeezers
Devin J. Dean, Taewon Park, Lars S. Madsen +12
Recent experiments have demonstrated the successful generation and detection of moderately squeezed vacuum states with integrated photonics. However, in order to benefit from the r…
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…
Occlusion-Aware Multimodal Beam Prediction and Pose Estimation for mmWave V2I
Abidemi Orimogunje, Hyunwoo Park, Kyeong-Ju Cha +3
We propose an occlusion-aware multimodal learning framework that is inspired by simultaneous localization and mapping (SLAM) concepts for trajectory interpretation and pose predict…
Robotic chip-scale nanofabrication for superior consistency
Felix M. Mayor, Wenyan Guan, Erik Szakiel +2
Unlike the rigid, high-volume automation found in industry, academic research requires process flexibility that has historically relied on variable manual operations. This hinders…
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…
Integrated phononic waveguide on thin-film lithium niobate on diamond
Sultan Malik, Felix M. Mayor, Wentao Jiang +6
We demonstrate wavelength-scale phononic waveguides formed by transfer-printed thin-film lithium niobate (LN) on bulk diamond (LNOD), a material stack that combines the strong piez…
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…
