Abstract
The study of the spectral switches has been extended to the off-axis regime within the framework of the paraxial approximation, and the main attention is focused on the influence of the off-axis parameters and incident angles on the behavior of the spectral switches. It is shown the critical position uc, spectral minimum Smin and transition height Δ of the spectral switch depend on the off-axis parameters Δu and incident angles φ. By a suitable choice of system parameters, Smin, Δ and zc of the spectral switch can be variable. Therefore, this kind of spectral changes might find some interesting applications in spectrum-selective interconnects. The on-axis Gaussian beams are treated as a special case of the general result. Keywords: modern optics, aperture diffraction, spectral switch, off-axis Gaussian beam
