This paper presents optically pumped solid-state organic lasers based on tris(8-hydroxyquinoline) aluminum (Alq3) doped with the laser dye 4-(dicyanomethylene)-2-t-butyl-6(1,1,7,7-tetramethyljulolidy 1-9-enyl)-4H-pyran (DCJTB, 2 wt %) using resonator which offers one dimensional distributed feedback. The lasers have been fabricated by deposition of organic films on top of suitable grating microstructures etched into SiN layer. The devices operating in the red spectral region are highly efficient and exhibit low threshold for oscillation (0.3 kW/cm2). The operating characteristics of the lasers are investigated in detail. The laser oscillation is obtained by optimizing the organic film thickness. The ratio of slot width to grating period is another important parameter to decrease the lasing threshold.
