Abstract
Two off-channel nonlinear defects coupled to the photonic
waveguide constitute the Fabry-Perot interferometer (FPR). The
defects are made from a Kerr-like nonlinear material. For the
linear case such a FPR can support the bound states in the form of
standing waves between the defects if the distance between them is
quantized. For the nonlinear case the bound states appear for
arbitrary distance between the defects however for an quantized
electromagnetic intensity. For the transmission through FPR we
reveal new resonances and show these are a result of coupling of
the bound states with incident wave because of nonlinearity of the
defects. The resonances are spaced at the eigen frequencies of
bound states.
