Abstract. Semiconductor heterostructures with prescribed energy dependence of
the transmittance can be designed by combining: {\em a)} Pad\'e
approximant reconstruction of the S-matrix; {\em b)} inverse scattering
theory for Schro\"dinger's equation; {\em c)} a unitary transformation
which takes into account the variable mass effects. The resultant continuous
concentration profile can be digitized into an easily realizable
rectangular-wells structure. For illustration, we give the specifications
of a 2 narrow band-pass 12 layer $Al_cGa_{1-c}As$ filter with the high
energy peak more than {\em twice narrower} than the other.
