“…However, these static holograms do not provide any modulation capability post-fabrication. Integration of LCs with metallic nanostructures has been previously demonstrated [18][19][20][21][22][23], however, these devices mainly provide the functionality for tunable optical filtering in the form of spectrally shifting transmission peaks and operate outside of the visible frequency range in the near to mid-infrared region.…”

Digital holography requires arrays of small reconfigurable elements to achieve complex reconstruction of the hologram with common systems based on pixels utilizing liquid crystal on silicon (LCoS) technology. The backplane of a typical pixel element is potentially underutilized and thus relatively large physical areas exist in which information can be stored and exploited to give additional functionality to pixel elements. Polarisation and wavelength dependent optical properties can be achieved in small areas using the plasmonic effects of optical antennae. The integration of LCs with optical antennae‐based plasmonic holograms allows active modulation of the far field pattern. The work here demonstrates the concept that conventional LCoS pixel elements can be greatly enhanced with the integration of plasmonic holograms, composed of optical antennae patterned on the surface, giving rise to new levels of modulation capability for holographic pixel elements. Using LCs, polarisation dependent effects in plasmonic holograms can be switched. ‘Engineered pixels', with sub‐wavelength multiplexing over both polarisation and wavelength, can increase the channel capacity of a typical LC display device.

“…These range from changing the LC cell geometry and electrodes design, [2][3][4][5][6][7][8][9][10][11] to changing the LC structure from cholesteric to blue phase (BP). [12][13][14][15][16] Jo et al 8 combined two different LC cell architectures, the vertical alignment (VA) in the initial state and the four-domain twisted nematic (FDTN) with an external field stacking the VA layer onto the planar alignment layer, resulting in a rise time of 13 ms and a driving voltage of 6 V. TaeHoon Yoon et al 9 introduced a three-terminal electrode structure to simultaneously apply an in-plain and a vertical electric field, to show both bright state and grey levels, with the slowest grey-to-grey response of 9.6 ms and from grey to zero in less than 1 ms. Hun Ki Shin and collaborators 10 proposed a polarization switching device using an optically compensated pi cell for polarization-glass-type threedimensional display with a total dynamic response time of 2.5 ms. Won-Kyu Lee and collaborators 11 developed a new LC alignment layer combining single wall carbon nanotubes (SWNT) with a conjugate block copolymer and conventional rubbing, Yielding a high response time (3.8 ms), low operation voltages (1.3 V), and high thermal stability.…”

“…To overcome this problem, several AOB devices based on liquid crystals (LCs) have been reported. [21][22][23][24][25][26][27] The LC AOB devices operate with low illumination because LCs have large NLO activity. The LC AOB devices reported are rather slow, but two-dimensional (parallel) data processing is possible.…”

An all-optical bistable (AOB) resonator device composed of a 430-nm-thick liquid crystal (LC) layer embedded in two thin gold films (MLM) is reported in this paper. This device allows the use of the incident illumination at normal incidence, whereas the previous AOB devices based on twisted nematic (TN)-LC function only for illumination at oblique incidence. The fastest switching time was measured to be 1.8 ms, which is significantly faster than that of TN-LC. Because the MLM device operates free from electronic circuits, it is promising for two-dimensional optical data processing, random access optical memories, and spatial light modulators.
