Optically pumped organic semiconductor lasers are fabricated by spin-coating a thin film of a methyl-substituted ladder-type poly-(para-phenylene) onto a nanopatterned circular grating distributed Bragg reflector. Varying the period of the grating allows for tunability of the laser wavelength. Comparing the emission spectra below and above threshold it shows that the lasing is spectrally located at the band-edge of the Bragg dip. This is in excellent agreement with the calculated dispersion relation of the laser system.
