Abstract
We have investigated some of the properties of distributed‐feedback lasers constructed in thin‐film optical waveguides deposited on anisotropic substrates. We describe TE or TM mode suppression, frequency tuning by varying the propagation direction relative to the substrate optic axis, and the generation of unexpected frequencies via a new type of distributed‐feedback interaction.Keywords
