    摘要: A method for forming a grating in a photorefractive composition comprising the steps of: providing a photorefractive composition containing a sensitizer and a polymer, wherein the polymer includes a first repeating unit which includes a moiety selected from the group consisting of the formulae (Ia), (Ib) and (Ic) as defined herein; and irradiating the photorefractive composition with a near infrared (NIR) laser, wherein the composition provides long grating holding time and the grating signal can be read out without external bias voltage.

    摘要: Described herein are optical devices comprising a photorefractive layer and at least two inert layers, such that the photorefractive layer is sandwiched between the two inert layers. The photorefractive layer may include a photorefractive composition that is photorefractive upon irradiation by a laser beam. In some embodiments, the photorefractive composition is formulated such that a grating that is irradiated into the photorefractive composition can be read out of the photorefractive composition without applying an external bias voltage. Furthermore, a grating that is written into the composition may be controlled using thermal treatment.
