Soluble fullerene derivative in liquid crystal: polymer composites and their impact on photorefractive grating efficiency and resolution.
نویسندگان
چکیده
By using soluble fullerene derivative [60]PCBM, we improved photorefractive efficiency in polymer-liquid crystal composites in comparison to previous works on similar materials. We show the effect of polymer network results in resolution and bandwidth improvements compared to pure liquid crystals. This is explained by the introduction of a charge trapping mechanism, providing a memory effect for the composite. Based on this effect, we propose an approach for designing composites with higher grating efficiency and resolution.

The photorefractivity of a photorefractive composite consisting of poly(N-vinylcarbazole) (PVK) doped with a non-room-temperature liquid crystal, 4-butyloxy4’-cyanobiphenyl (4OCB), and C60 was studied by means of measuring the two-beam coupling coefficients. The results show that the photorefractivity is enhanced by phase separation. PACS: 42.65; 61.30; 61.40 Interest in materials that exhibit ...

متن کاملPrism grating using polymer stabilized nematic liquid crystal
A prism grating using polymer stabilized liquid crystal was fabricated and its diffraction characteristics evaluated. Such a prism grating exhibits not only a periodic grating structure but also a prism-like gradient refractive index within each grating period. As a result, the diffraction behavior is asymmetric. The first order exhibits high diffraction efficiency while the zeroth order has a ...

متن کاملElectrically-switchable, polarization-independent diffraction grating based on negative dielectric anisotropy liquid crystal
An atomic force microscope is used to scribe polymer-coated substrates to create an electrically-controlled polarization grating. The grating is nondiffracting in the voltage-off state and diffracting in the voltage-on state. Based upon an optical phase difference of approximately π between adjacent pixels, the grating’s efficiency is independent of optical polarization and can be prepared for ...
