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…
Arbitrary electro-optic bandwidth and frequency control in lithium niobate optical resonators
Jason F. Herrmann, Devin J. Dean, Christopher J. Sarabalis +6
In situ tunable photonic filters and memories are important for emerging quantum and classical optics technologies. However, most photonic devices have fixed resonances and bandwid…
Efficient Photonic Integration of Diamond Color Centers and Thin-Film Lithium Niobate
Daniel Riedel, Hope Lee, Jason F. Herrmann +11
On-chip photonic quantum circuits with integrated quantum memories have the potential to radically progress hardware for quantum information processing. In particular, negatively c…
Platform-agnostic waveguide integration of high-speed photodetectors with evaporated tellurium thin films
Geun Ho Ahn, Alexander D. White, Hyungjin Kim +8
Many attractive photonics platforms still lack integrated photodetectors due to inherent material incompatibilities and lack of process scalability, preventing their widespread dep…
Integrated Passive Nonlinear Optical Isolators
Alexander D. White, Geun Ho Ahn, Kasper Van Gasse +4
Fiber and bulk-optical isolators are widely used to stabilize laser cavities by preventing unwanted feedback. However, their integrated counterparts have been slow to be adopted. W…

Photonic modal circulator using temporal refractive-index modulation with spatial inversion symmetry
Jiahui Wang, Jason F. Herrmann, Jeremy D. Witmer +2
It has been demonstrated that dynamic refractive index modulation, which breaks time-reversal symmetry, can be used to create on-chip non-reciprocal photonic devices. In order to a…
Ultra-low-power second-order nonlinear optics on a chip
Timothy P. McKenna, Hubert S. Stokowski, Vahid Ansari +7
Second-order nonlinear optical processes are used to convert light from one wavelength to another and to generate quantum entanglement. Creating chip-scale devices to more efficien…
