A semiconductor material emitting device is positioned such that its output flux impinges on a substrate at a non-perpendicular angle, so as to grow a first epilayer which is linearly graded in the direction perpendicular to the growth direction. The linear grading can be arranged such that, for example, each row of pixels has a different cutoff wavelength, thereby making it possible to provide a spectroscopic FPA without the use of filters. The non-perpendicular angle and/or the flux intensity can be adjusted to achieve a desired compositional grading. A spectral ellipsometer may be used to monitor the composition of the epilayer during the fabrication process, and to control the intensity of the flux.
