It seems that no one has responded.

TIFF is (by definition) primarily a raster format which may be 
augmented with additional data.  It does not make sense without a 
raster image.  Without a raster image, it is unlikely that any other 
software will ever read your format.

Perhaps you should consider a more vector-oriented standard format 
like SVG which can be used to incrementally produce a raster image of 
any size from your photon data.  Certain "plot" oriented formats may 
also work.
