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.
