Using the theory for electron energy spectrum and oscillator strengths of inter-subband quantum transitions, developed in the model of position-dependent effective mass and rectangular potentials, the geometrical design for the compact cascade of a quantum cascade detector (with a two-well active region) operating in far infrared range is proposed.  The extractor of the cascade is optimized in such a way that the energy steps of its phonon ladder resonate with optical phonon energy, providing effective phonon-assisted tunneling of electrons between the active regions of  cascades.  It is shown that increasing thickness of the barrier between the wells of active region, causes the broadening of detector absorption band due to the bigger distance between energy levels in anti-crossing.
