Abstract
We report on the distributed-feedback dye laser based on the polymeric multilayer structure and rhodamine 6G. The periodic structure of the one-dimensional photonic crystal was fabricated by spin coating technology and alternately stacking of high and low refractive-index polymers. One of the polymeric layers consists of nanoparticles to change the effective refractive index. The multilayer showed a photonic bandgap in the transmission spectrum and the surface-emitting laser output was obtained at the blue side band-edge under the excitation of the second harmonic of a Nd:YAG laser. Wavelength tuning of the laser peak was possible by changing the doping density of the nanoparticles.
期刊介绍：
Optical Materials has an open access mirror journal Optical Materials: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review.
The purpose of Optical Materials is to provide a means of communication and technology transfer between researchers who are interested in materials for potential device applications. The journal publishes original papers and review articles on the design, synthesis, characterisation and applications of optical materials.
OPTICAL MATERIALS focuses on:
• Optical Properties of Material Systems;
• The Materials Aspects of Optical Phenomena;
• The Materials Aspects of Devices and Applications.
Authors can submit separate research elements describing their data to Data in Brief and methods to Methods X.
