Acoustic distributed feedback (ADFB) lasers with stripe active regions for current injections have been theoretically analysed. The theory is based on a coupled-mode analysis employing Bragg guided modes. The characteristic equation of oscillation for the two-dimensional DFB laser is derived in an explicit form. The mode spectra and the threshold gains for the onset of the oscillation of the ADFB laser are obtained, and the characteristics of the two-dimensional mode structure is discussed. Also discussed is the effect of complex photoelastic constants.
