(Color online) Basic structure of the laser investigated: substrate with a structured resist coating. The gain medium is mixed into the UVII-HS resist.
(Color online) Calculated band diagram of the structure pictured in Fig. 1. The period of the structure equals 400 nm The area outlined by the rectangular is enlarged in Fig. 3.
(Color online) Enlargement of the rectangular area outlined in Fig. 2. The white squares represent the data from the calculations, the measured emission is plotted in graytones.
(Color online) Emission spectra taken for three different pump pulse energies. The inset shows a top view scanning electron microscopy picture of the interferometrically structured laser devices.
