This thesis presents a study of lasing properties and optical amplification in semiconducting conjugated polymers and dendrimers. Configured as surface-emitting distributed feedback lasers, the effect of incorporating wavelength-scale microstructure on the output of the devices …

High-power sources of terahertz (THz) radiation (frequency 1 THz–10 THz, wavelength 300 μm–30 μm) are highly desired for applications in chemical and biomolecular sensing such as detection and analysis of drugs and explosives, biomedical imaging, remote-sensing of Earth's atmosp…
