Polarization-independent photochromic diffraction in dye-doped liquid crystal

Not Accessible

Your library or personal account may give you access

Abstract

We report the observation of polarization independent photochromic diffraction in an azo dye doped liquid crystal. For the first time, to our knowledge, photochromic phase modulation and light diffraction, exhibiting over 90% polarization independence for both writing and probe beams, were produced in an anisotropic liquid crystalline material.
