Radiation due to six canonical configurations for the source current density embedded in a structurally chiral medium is analyzed theoretically. The radiation spectrum is highly dependent on whether its source is co-chiral or cross-chiral, and is localized either in or on the edges of the Bragg regime. The obtained conclusions hold for both chiral liquid crystals and chiral sculptured thin films doped with fluorescent dyes, etc.
