pulse shaper
The device takes a light pulse, splits it with a prism like component, then offset different part of the spectrum in time.
Let's first implement this as a phase shifter. We take a range in the spectrum and offset the phase inside a window. This seems to be a bad idea as it generates signal everywhere, and we can't control the time offset arbitrarily.
