All-fiber Mach-Zehnder interferometer

[boxfullofvacuumtubes]

Experimentalists, would you mind sharing your experience building a fiber-based Mach-Zehnder interferometer? What equipment did you use? How hard is it to achieve the same length of both arms with the fiber and couplers that you can buy online? And how sensitive is the resulting interferometer to vibrations, temperature changes, etc.?

I do have one input that you might find useful, basically about interferometry, including the use of Fresnel coefficients in interferometry, that you might find useful. About a year ago, I wrote an Insights article for Physics Forums which discusses the fundamentals of interferometry: https://www.physicsforums.com/insights/fabry-perot-michelson-interferometry-fundamental-approach/ $\\$ As for the case of an interferometer that uses fiber optic components, I don't have any experience with that particular application.
