Seriously, where are our shield generators or photon shields like those in star trek? Are these completely science fiction or why haven't we came up with something similar?

Technically 'photon shields' do exist - we call them electromagnetic fields though. Controlling them is rather difficult but in their singular component of either an electric or magnetic field, they are more manageable. But then there's the issue of making them powerful enough to produce the effects that one is after without it damaging the object that it's trying to protect: the Earth does it pretty well against charged particles from the Sun with its magnetic field but it's nowhere near 100% effective.
