Ultra-narrow linewidth single-frequency fiber lasers (<1 kHz) are critical for applications like coherent optical communications, gravitational wave detection, and high-precision metrology. However, thermal noise in the fiber Bragg grating (FBG) and gain medium introduces phase fluctuations, ultimately limiting the achievable linewidth.
