  We present the advantages of supercontinuum generation in chiral, therefore
circularly birefringent, all-normal dispersion fibers. Due to the absence of
nonlinear power transfer between the polarization eigenstates of the fiber,
chiral all-normal dispersion fibers do not exhibit any polarization
instabilities and thus are an ideal platform for low-noise supercontinuum
generation. By pumping a chiral all-normal dispersion fiber at 802 nm, we
obtained an octave-spanning, robustly circularly polarized supercontinuum with
low-noise.
