A device for the optical processing of electrical signals. An optical source (L) emits a multiple-wavelength optical beam (B1). A modulator (MOD) modulates this beam. An optical fiber (F) receives the modulated beam and delays the components corresponding to the different wavelengths differently. A dispersive...http://www.google.de/patents/US5428697?utm_source=gb-gplus-sharePatent US5428697 - Device for the optical processing of electrical signals
