Abstract
Amplified spontaneous emission (ASE) and distributed feedback (DFB) lasing of conjugated compound in various polymer matrices were presented. Effective and large ASE intensity, lowest threshold and maximum optical gain were measured in poly(styrene) matrix. Sharp DFB lasing with FWHM = 0.6 nm was measured at 490 nm. The lasing wavelength of 490 nm was fitted well by the theoretically calculated value of 491 nm.
