Abstract : A semiconductor multi-color filter spectrum analyzer is created by multiple epitaxial layers of varying composition. A DC sweep voltage is used to successively deplete the epitaxial layers. An AC voltage is used to modulate the absorption edge of the individual layers. A modification of this device concept is a bandwidth detector in which the spectral band width is a function of the applied DC voltage.
