Abstract :
An electrooptic integrated optics spectrum analyzer is investigated in which an electrode array with a spatially varying period performs the functions of the collimation and transformation lenses and of the signal introduction. The device yields a weighted discrete Fourier transform (DFT) of the voltages on the electrodes. An implementation of the device would be fully compatible with planar photolithographic processes.
