title: Grating coupled compound resonators.
abstract: A simple model, based on a simple boundary condition at the grating coupling surface, is constructed for a grating coupled cavity. The physical meaning of the boundary condition is discussed, and the gain factor and phase shift of the coupled resonator are studied in terms of the properties of the grating and the reflectivities of the mirrors.
