We present a new way of measuring chirality, via the spectral shift of photonic band gaps in one-dimensional
structures. We derive an explicit mapping of the problem of oblique incidence of circularly polarized light on
a chiral one-dimensional photonic crystal with negligible index contrast to the formally equivalent problem
of linearly polarized light incident on-axis on a non-chiral structure with index contrast. We derive analytical
expressions for the first-order shifts of the band gaps for negligible index contrast. These are modified to
give good approximations to the band gap shifts also in the case of appreciable index contrast. We believe
that this may potentially be used for measuring enantiomeric excess.
