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…
