Circularly polarized light-induced rearrangement of optical axis in photoanisotropic recording media

The rearrangement of the optical axis in reversible photoanisotropic media under the action of a circularly polarized beam is demonstrated and quantitatively measured. These results are used to clarify the term "optical erasure" in reversible storage media. The detected residual anisotropy...

Description
Summary:The rearrangement of the optical axis in reversible photoanisotropic media under the action of a circularly polarized beam is demonstrated and quantitatively measured. These results are used to clarify the term "optical erasure" in reversible storage media. The detected residual anisotropy is taken into account to estimate the degradation of the signal to noise ratio in a storage device with a tilted readout design. ©
