This letter examines a planar cholesteric cell (CLC) doped with a collocation of two laser dyes as a one-dimensional photonic crystal. Adding the photo-tunable chiral material-AzoB allows the CLC photonic crystal can be lased at the band edges of the photonic band gap with a tuning range of over 100nm. Tuning is performed by irradiating the chiral AzoB material with UV light so that it undergoes trans-cis isomerization in the CLC film. The tuning range is the visible region from 563nm to 667nm. Moreover, the tuning is reversible.
