The theory of bioluminescent emission from a chiral sculptured thin film (STF) of finite width but infinite lateral extent is formulated. The photon source filaments embedded in the chiral STF are modelled as either co-wound or contra-wound. The structural handedness as well as the periodicity of the chiral STF are shown to critically control the emission spectrum and intensity, while the polarization state of the emitted light is strongly correlated with the structural handedness of the source filaments.
