Abstract
We quantitatively investigate the performance of holographic data storage system with Spatial Quadrature Amplitude Modulation datapages in which intensity and phase modulations are combined. The phase-shift required for phase demodulation is embedded in the datapage. Root Mean Square Error of demodulated phase value and Symbol Error Rate are experimentally evaluated.
