Abstract:We report a vertical microcavity dye laser consisting of a polymeric active random layer doped with silica nanoparticles whose diameters are approximately 100 nm. Pumped by an InGaN-based blue-violet laser diode with pulse duration of 3 ns, single mode laser oscillation was obtained at a wavelength of 530 nm. The threshold pump power decreased from 70 mW/pulse to 49 mW/pulse by adding nanoparticles to the active layer. We found an optimum particle density of 2×10 13 cm −3 by measuring threshold pump power to change depending on the particle density in the activity layer.

Reflecting recent progress in the functionalization of roll-to-roll processed polymer multilayers, this review describes the development and characterization of versatile large-area multilayer distributed feedback (DFB) lasers. These developments are reviewed in the broader context of microresonator lasers, with a brief tutorial on the theory and experiment needed to understand their unique features. Of particular interest is the broad tunability of these DFB lasers by simple modification of their structure, mechanical stretching, and temperature. Prospects for commercialization of polymer multilayer DFB lasers are also discussed.

“…Currently, both the microsphere and the microtoroid resonator are known to have ultrasmooth surfaces (as demonstrated by their cavity Q factors > 100million); therefore, they are ideal master structures. [9, 10] To achieve the second two criteria, we utilize a molding polymer with low optical loss and tapered optical fiber waveguides, which have low coupling loss.In the present work, the initial master used is the ultra-high-Q microtoroid [4]. These silicabased structures exhibit very low surface roughness as evidenced by Q factors in excess of 100 million.…”
