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…
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…
Photonic Millimeter-wave Generation Beyond the Cavity Thermal Limit
William Groman, Igor Kudelin, Alexander Lind +11
Next-generation communications, radar and navigation systems will extend and exploit the higher bandwidth of the millimeter-wave domain for increased communication data rates as we…
