Description

Fluctuation of light phase occurence in a fiber Mach-Zehnder interferometer used as an antenna for gravitational wave recording in a kHz frequency range is discussed on the base of statistical physics and thermodynamics. Thermodynamic fluctuation of entropy and pressure appears to be the main source of phase fluctuation. It is shown that these fluctuations limit the sensitivity of opticofiber antenna. In particular, under 30 km arm length in interferometer and 10 K temperature the antenna sensitivity to dimensionless amplitude of a gravitational wave makes up ∼ 10-20. 9 refs
