We have investigated optical properties of dye-encapsulated dendrimers for photonic application and observed several interesting behavior, such as controlled intermolecular interactions, super-radiance, and supernarrowing laser emission. A supernarrowing laser spectrum was obserbed without using any resonator mirrors due to moderate scattering caused by densely doped dendrimer aggregates in a polymer wavegaide. Weak scattering from the aggregated dendrimers in the host polimer matrix with gain is responsible for photon locarization.
