Photonic Generation and Free-Space Distribution of Millimeter Waves for Portable Optical Clocks
Dylan Meyer, Alexander Lind, William Groman +7
Robust and portable optical clocks promise to bring sub-picosecond timing instability to smaller form factors, offering possible performance improvements and new scenarios for posi…
Ultralow noise microwaves with free-running frequency combs and electrical feedforward
Takuma Nakamura, William Groman, Qing-Xin Ji +11
Optically generated microwave signals exhibit some of the lowest phase noise and timing jitter of any microwave-generating technology to date. The success of octave-spanning optica…
Chip-scale modulation-free laser stabilization using vacuum-gap micro-Fabry-Pérot cavity
Mohamad Hossein Idjadi, Haotian Cheng, Farshid Ashtiani +5
Narrow-linewidth lasers are vital for a broad range of scientific and technological applications, including atomic clocks and precision sensing. Achieving high frequency stability…
Sub-femtosecond stabilization of multicore fiber for high-fidelity quantum networking at 100% duty cycle
Takuma Nakamura, Nazanin Hoghooghi, Nicolas Fontaine +8
Originally envisioned as a solution for the capacity crunch in telecommunications networks, multicore fibers (MCF) are contributing to scientific fields beyond telecom, such as sen…
From ultra-noisy to ultra-stable: optimization of the optoelectronic laser lock
Takuma Nakamura, Yifan Liu, Naijun Jin +5
We demonstrate thermal-noise-limited direct locking of a semiconductor distributed feedback (DFB) laser to a sub-1 mL volume, ultrastable optical cavity, enabling extremely compact…
Dual Laser Self-Injection Locking to a Micro Fabry-Perot for Low Phase Noise Millimeter-wave Generation
William Groman, Naijun Jin, Haotian Cheng +8
Low-noise and accessible millimeter-wave sources are critical for emergent telecommunications, radar and sensing applications. Current limitations to realizing low-noise, deployabl…
