An "Aha" moment for me! I slowly begin to understand how Chromosol's patented device works. This is a page from their patent:

Figure 4 is the device, with a laser light source ("probe laser"), which I assume is a constant light source. The top (dark) layer is "a region containing rare earth or transition metal ions for generation of radiation of a predetermined wavelength. Said region includes an organic complex comprising a ligand adapted to enhance the emission of radiation and a chromophore separately co-operable with a radiation source of wavelength not greater than that of said predetermined desired radiation". Then there is the "pump laser", which I assume is intermittent and encodes data.

When the pump laser is on, the light signal is amplified, as shown on Figure 5. That's how data is transmitted via pulses of light.
