A Stern–Gerlach device uses magnets to seperate out fermions like electrons
into beams of spin +1/2 and spin -1/2 particles, a SG device won't work for
a beam of boson such as photons. To do something comparable and separate
spin +1 photons from spin -1 photons you'd use a polarizing filter not a
magnet.
