We present feedback structures for an organic photonic crystal laser created by directly structuring the gain medium, consisting of UVII-HS resist doped with a mixture of the laser dyes Coumarin and DCM. The photonic-crystal structure is realized by means of interference lithography. This approach greatly reduces the number of steps required to realize the feedback structure of an organic laser. The dispersion relations obtained expermimentally agree very well with the simulated band diagram.
