AB  - We demonstrate a pulse-shaping technique that allows for spectrally resolved 
      splitting of an input signal to multiple output ports. This ability enables 
      reconfigurable creation of splitters with complex wavelength-dependent splitting 
      ratios, giving similar flexibility to a Field Programmable Gate Array (FPGA) in 
      electronics. Our technique can be used to create reprogrammable optical 
      (interferometric) circuits, by emulating their multi-port spectral transfer 
      functions instead of the traditional method of creating an interferometer by 
      splitting and recombining the light with an added delay. We demonstrate the 
      capabilities of this technique by creating a Mach-Zehnder interferometer, an 
      all-optical discrete Fourier transform filter, two nested Mach-Zehnder 
      interferometers and a complex splitter with a triangular-shaped response.
