Abstract
A picosecond flat-top pulse shaper using an abrupt taper interferometer is
proposed and experimentally demonstrated. A theoretical model based on
coupled mode equations is also derived to simulate the propagation of
picosecond pulses through the abrupt taper interferometer. Through properly
designing the abrupt taper interferometer, a 3.8-ps flat-top pulse with less
than 4% ripple is successfully generated from a 2.2-ps Gaussian pulse. The
proposed technique can also be used in the sub-picosecond regime.
