The emission of polymer distributed feedback lasers is tuned by integrating nonlinear optical organics. The nonlinearity allows reversible tuning of the amplified spontaneous emission of a conjugated polymer by 30 nm, and the lasing wavelength by 17 nm, with a lasing tunability coefficient of 0.17 nm/V.
