Laser action studies of π-conjugated polymer microcavities
(IEEE, 2008)Unidirectional laser emission was observed from φ-conjugated polymer microcavities with spiral geometry, and from microdisks containing line defects. For both type of cavities directionality contrast of the laser emission ... -
Ultralow threshold laser action from toroidal polymer microcavity
(American Institute of Phycsics, 2009)We report laser action from a toroidal microcavity coated with π-conjugated polymer. An ultralow threshold value of ∼200 pJ/pulse is achieved by free space excitation in ambient conditions. This is the lowest threshold ...
