N2 - Precise emission wavelength modeling is essential for understanding and optimization of distributed<br/>feedback (DFB) lasers. An analytical approach for determining the emission wavelength based on<br/>setting the propagation constant of the Bragg condition and solving for the resulting slab waveguide<br/>mode is reported. The method is advantageous to established methods as it predicts the wavelength<br/>precisely with reduced complexity. Four-layered hybrid polymer-TiO2 first order DFB dye lasers with<br/>different TiO2 layer thicknesses are studied. Varying the TiO2 thickness from 0 nm to 30 nm changes<br/>the emission wavelength by 7nm with compelling agreement of modeling results to experimental<br/>measurements
