Two possible solutions:
1) Your photon 'count' may not be high enough (or photon 'spacing' might be too
high.)
2) Photon 'jitter' has a default of .4, I think. That usually results in a
slight 'banding appearance' of the photon caustics. Try using a higher value
like 1.0 instead, to see if that helps. (As an experiment, set it to 0.0 first,
to see if that makes the problem *worse*.)

Your object is obviously very close to the light_source, causing the
photons to spread a lot. What you see is not a grid but a distorted spiral.
This is caused by the spiraling pattern used to shoot photons.
Try increasing count by something like *4, if you use count, or reducing
spacing by half, if you use spacing.
Also, you may try using jitter 0.5 to 1.0 in the photons block in the
global_settings.
If you intend to use an area_light later, add photons{area_light} in the
light's definition. Not always usefull, but can make a huge difference
in this case.
