Abstract A two-dimensional diffraction theory of an open strip resonator embedded in a umaxially anisotropic medium is presented. Applying the modified Kirchhoff approximation and a Green's function technique, the problem is reduced to the solution of a system of two coupled, homogencous integral equations for the unknown field distributions on the mirrors. The eigenvalues of this system of integral equations are related to the characteristic (complex) frequencies of the modes of the open resonator by an implicit relationship. The eigenvalues as well as the corresponding characteristic frequencies are calculated numerically. From the characteristic frequency of a mode, its resonance frequency, its diffraction loss and its quality factor follow immediatedly. For various resonator configurations the influence of the orientation of the optical axis of the uniaxial medium on the properties of the modes is studied in detail.
