Fourier pulse-shaper-based high-order differential group delay emulator.
We demonstrate a Fourier pulse-shaper-based differential group delay (DGD) emulator which can be programmed to possess arbitrary user-specified frequency dependent DGD profile. The DGD produced can be up to 400ps range with <1ps accuracy. Generated frequency-dependent DGD profiles are in excellent agreement with numerical simulations.
