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 sub-terahertz cavity electro-optic transduction
Kevin K. S. Multani, Jason F. Herrmann, Emilio A. Nanni +1
Emerging communications and computing technologies will rely ever-more on expanding the useful radio frequency (RF) spectrum into the sub-THz and THz frequency range. Both classica…
