Don't recall the German/Russian poster angle either.
Found it though digging. Good call with the 20-F form.

POET’s technology platform for optoelectronic integration is designed to exploit the optoelectronic and electronic behaviors of GaAs semiconductor material. One of the benefits of this material, from a space electronics perspective, is that GaAs is significantly less susceptible to x-ray and gamma-ray total integrated dose radiation. GaAs has been a long-standing choice for high-frequency devices and circuits, though GaAs digital devices do not provide the performance that metal oxide semiconductor field effect transistor devices provide. Currently, the POET platform is being utilized within a NASA deep space probe initiative.
