Abstract

In this study, we synthesized the new spirobifluorene derivatives; hexylbiphenyl-spirobifluorene (HBP-Spiro) and demonstrated the operation of a distributed-feedback polymer waveguide blue laser. The experimental laser slope efficiencies of over 10% were obtained for a pump-pulse duration of 35 ps at a wavelength of 355 nm.
