摘要
A polarisation-independent blue-phase liquid crystal microlens using an optically hidden dielectric structure is proposed. In this design, the non-uniform electric field across the lens aperture is obtained by the modulation of the effective dielectric constant of an optical hidden layer. As the applied voltage varies from 0 to 150V(rms), the focal length of the lens can be tuned from to 16.6mm. Simulation results show that this device has a parabolic-like profile and exhibits polarisation-independent property. [GRAPHICS] .
