Abstract :
We present a systematic method for designing spectral diversity filters using 2D and 3D photonic crystals. These filters convert an incoherent input beam with uniform spectral content over the input dimension into a desired nonuniform spatial-spectral pattern. Such spectral diversity filters can be used for designing compact spectrometers that can be used for the detection of Raman signatures in biosensors.
