We investigate an amplified spontaneous emission phenomenon and lasing in a two-layer system: a layer of modified deoxyribonucleic acid (DNA) polymeric matrix containing dye which is superimposed on a periodic relief structure formed in photochromic polymer. The luminescent layer was prepared from DNA blended with cationic surfactant molecule cetyltrimethyl-ammonium chloride (CTMA) and a Rhodamine (Rh6G) laser dye. This layer covered a specially designed photochromic polymer layer in which a surface relief grating was inscribed by holographic method in order to form a Bragg reflector for photons. Thin film of the DNA-CTMA:Rh6G/photochromic polymer was excited with pulsed laser.
