10 $^{- 15}$ -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…

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…
