Major Field of Science: | Engineering and Technology | Field Category: | Mechanical Engineering | Ημερομηνία Έκδοσης: | 1-Δεκ-2005 | Πηγή: | Applied Physics Letters, 2005, vol. 87, iss. 26, pp. 1-3 | Volume: | 87 | Issue: | 26 | Start page: | 1 | End page: | 3 | Περιοδικό: | Applied Physics Letters | Περίληψη: | We report on amplification of blue light (469 nm) via amplified spontaneous emission in asymmetric planar waveguides of a fully arylated polyindenofluorene derivative. A very low threshold value of about 3 μJ cm2 (∼375 W cm2) for amplification of light has been demonstrated by pumping the waveguides at 3.0 eV (410 nm) with a stripe shape excitation beam. Moderate gain coefficients up to 21 cm-1 and loss coefficients around 6 cm-1 have been measured. All measurements were performed under ambient conditions. No sample degradation could be observed which testifies to the excellent stability of the material against photodegradation. © 2005 American Institute of Physics. | Description: | Funding text The authors acknowledge financial support by the German Ministry of Science and Education, Project OLAS, 13N8168.
