Take a laser source with small bandwidth centered around the average frequency (or wavelength)
With an hypothetical external modulator that can switch as fast as we want, ca we make a pulse that is spatially shorter than 1 wavelength?
If not? Why? What would that entail?
Clearly the number of photons always need to be an integer in whatever pulse we have, right?
