Abstract

Phase-shift-amplified interferometry (PAI) is demonstrated using a heterodyne detection scheme. We demonstrate a sensitivity amplification factor of 35, giving 7.9 · 10⁻⁴ rad, or 40 pm displacement, resolution. This was achieved due to the improved immunity of PAI to the total relative intensity noise (RIN) of the system. In addition, we predict a factor of √2 fundamental improvement to shot-noise-limited phase-shift sensitivity as compared to a regular heterodyne Mach-Zehnder interferometer.
