I notice that the caption describes a photon seive as containing
tens of thousands of pinholes. This does not sound like a very
easy device to produce.

My guess is that you would write a computer program to generate a large
original and then photo-reduce it in the
the difficulty involved in making a photon sieve is about the same as making
a polarizing filter

There may be a new kind of zone plate called the 'photon sieve'. Instead of
using clear and opaque concentric rings, it uses pinholes of decreasing diameter
arranged in rings related to the zone plate.
