Generalized fiber Fourier optics
Optics Letters, 2011A twofold generalization of the optical schemes that perform the discrete Fourier transform (DFT) is given: new passive planar architectures are presented where the 2 × 2 3 dB couplers are replaced by M × M hybrids, reducing the number of required connections and phase shifters.

In the following sections, we shall discuss a variety of field and laboratory measurements on telecommunication fibers, largely excluding sources, detectors and electronics. Certain of these measurements, especially bandwidth and attenuation, will often yield different results for different launching conditions.
