This is what it used to say i believe in 20 F.

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 evaluated in connection with a NASA deep space probe initiative

Now wording is quite different.

It sounds like POET is accepted and being used in military and NASA applications.
