Abstract

Thin film waveguides of polyphenylenevinylene were formed on a distributed feedback resonator. Light emission under pulsed optical pumping was measured as a function of excitation wavelengths. A distributed feedback lasing appeared constantly at 635 nm. In addition, an emission peak due to stimulated resonant Raman scattering emerged and its peak position shifted according to the excitation wavelength. When the latter peak just overlapped with the former one, the emission intensity was enhanced and its peak width and background noise by amplified spontaneous emission were reduced. The coupling of Raman scattering with the feedback mode would be a useful technology for development of a plastic laser.
