We present here tunable lasing from holographic distributed feedback (DFB) resonator of electroluminescent conjugated polymer waveguide. Tunable holographic lasing from 560 to 590 nm was simply achieved by rotating a Lloyd-mirror waveguide configuration. Lasing performance for the first order (m = 1) is superior to that for the second order (m = 2). Threshold for lasing for m = 1 is in the range of 25 to 50 μJ/cm2/pulse, which is close to that for amplified spontaneous emission (ASE), and that for m = 2 is larger than 104 μJ/cm2/pulse. For m = 1, slope efficiency of 7.3% including ASE in addition to lasing emission was measured, whereas for m = 2 slope efficiency between 0.1 and 0.2% was measured. © 2011 Elsevier B.V.
