Self-stabilization of microcombs
Krishna Twayana, Fuchuan Lei, Junyong Choi +2
Optical frequency combs form phase-locked spectral lines arranged on an equidistant grid fully defined by two degrees of freedom, i.e., the repetition rate and frequency offset. St…
Optical frequency comb integration in radio telescopes: advancing signal generation and phase calibration
Minji Hyun, Changmin Ahn, Junyong Choi +8
Very long baseline interferometry (VLBI) enables high-angular-resolution observations in astronomy and geodesy by synthesizing a virtual telescope with baselines spanning hundreds…
10-level laser stabilization down to fiber thermal noise limit using self-homodyne detection
Igju Jeon, Woosong Jeong, Changmin Ahn +1
We demonstrate a self-homodyne detection method to stabilize a continuous-wave 1550-nm laser to a 1-km optical fiber delay line, achieving a frequency instability of 6.3x10<sup>-15…
Palm-sized, vibration-insensitive and vacuum-free all-fiber-photonic module for 10-14-level stabilization of CW lasers and frequency combs
Igju Jeon, Changmin Ahn, Chankyu Kim +4
Compact and robust frequency-stabilized laser sources are critical for a variety of fields that require stable frequency standards, including field spectroscopy, radio astronomy, m…
