Solid-state dye-doped polymeric distributed-feedback lasers in near-infrared wavelength region were fabricated by photo nanoimprint lithography. Fluorinated-polyimide material which shows low propagation loss in the near infrared was used as the host matrix of the active waveguide doped with near-infrared organic dye, LDS950. Single wavelength lasing emission at 953 nm, which corresponds to the second-order Bragg reflection for the grating, was observed at room temperature from the laser by photo-pumping using nitrogen-gas laser. When the ambient temperature is raised, the lasing wavelength shifts to shorter at a ratio of 0.094 nm/K between 20 and 50°C, as the effective refractive index of the active region becomes smaller. The lasing threshold pumping density stays nearly constant during the temperature variation. © 2009 SPIE.
