The control of waveguided modes in light-emitting materials is an important goal in quantum optics. It would allow much greater modification of photon mode density than is possible with planar microcavities. Most of the light generated in an LED is waveguided and lost. We have approached this problem using lateral microstructure to control lateral (waveguide) modes. We have studied the effect of microstructure on photoluminescence (PL) from conjugated polymers. These materials are promising for LEDs, and (optically pumped) lasing behaviour has recently been demonstrated. They are convenient systems for the study of cavity QED because they can be readily deposited as wavelength-scale films by spin-coating. We report a strong modification of the luminescence spectrum by lateral microstructure.
