Various embodiments may provide a spatial light modulator. The spatial light modulator may include a first electrode arrangement. The spatial light modulator may also include a second electrode arrangement. The spatial light modulator may additionally include a liquid crystal (LC) layer between the first electrode arrangement and the second electrode arrangement. The spatial light modulator may also include one or more nanoantennas in contact with the liquid crystal layer. The first electrode arrangement and the second electrode arrangement may be each configured to allow at least a portion of light to pass through.

Spatial light modulator and method of forming the same

The present invention discloses a recording medium comprising an improved doped Stoichiometric Lithium Niobate (SLN) crystal for high-speed holographic data storage. The improved doped SLN has an extremely high optical damage resistance of more than 145 kW/cmfor power density of an incident laser beam along the c axis. The Recording time using the present improved doped SLN is advantageously very short and is about 1 second for a single hologram with a saturated diffraction efficiency of 28.7% at a recording laser beam density of 70 W/cm. Reliable retrieval of a signal-image written at as low as 1 milliseconds has been performed in the Z-cut doped SLN. The present recording medium is an improved doped SLN of a Z-cut SLN crystal doped with Iron (Fe) and Terbium (Tb). The Terbium (Tb) content within the fluxed melts for growing the improved doped SLN ranges from 10 ppm to 140 ppm.
