We present a bidirectional recirculating frequency-shifting
loop, seeded by a continuous-wave (cw) laser, to perform
multi-heterodyne interferometry. This fiber-optic system
generates two counter-propagating “acousto-optic” frequency combs with a controllable line spacing. Apart from
its simple architecture, coherent averaging allows us to
reach acquisition times up to the second scale without resorting to any active stabilization mechanism. We also show
that the relative phase between the combs is quadratic and
can be easily controlled by adjusting the parameters of the
loop. The capability of our scheme to perform molecular
spectroscopy is proven by dual-comb measurements of a
transition of hydrogen cyanide in the near-infrared region
(1550 nm). [-]
