Redefining the limits of real-time noise cancellation in optical fiber links
Charles A. McLemore, Marco Pomponio, Takuma Nakamura +4
A broad and growing array of applications rely on the faithful transmission of ultrastable optical signals over noisy paths, requiring cancellation of environmentally induced noise…
Fiber Link Stabilization with a Multicore Fiber Amplifier
Yifan Liu, Takuma Nakamura, Daniel J. Elson +7
We study the use of separate cores of a multicore erbium-doped fiber amplifier (MC-EDFA) in a noise-canceled link for ultrastable optical frequency transfer. We demonstrate fractio…
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…
