New perspectives on disorder in photonic materials are opened up by polyhedral oligomeric silsesquioxanes (POSS) dispersed at a molecular level in dye‐doped liquid and solid solutions. The optical homogeneity of these hybrid materials assures a coherent laser action, which is significantly enhanced by the stimulated emission multiply scattered by passive POSS centers.
