Webknown as cosmic birefringence because it is as if space itself behaved like a birefringent crys-tal (Komatsu , 2024). Emitted at the epoch of recombination and with its polarization angular power spectra ac-curately predicted by the standard cosmologi-cal model, the cosmic microwave background (CMB) is the ideal tool to measure birefrin-gence. 2. Weboptical measurements carried out below the glass transition temperature, the intrinsic birefringence was found to de crease with increasing k. For the sample k =0.7, the …

The significance of the birefringence is that optical materials can be cut to impose specific changes in the polarization of incident beams.
