    "abstract": "We propose a scheme which encodes information in both the longitudinal and\nspatial transverse phases of a continuous-wave optical beam. A split\ndetector-based interferometric scheme is then introduced to optimally detect\nboth encoded phase signals. In contrast to present-day optical storage devices,\nour phase coding scheme has an information storage capacity which scales with\nthe power of the read-out optical beam. We analyse the maximum number of\nencoding possibilities at the shot noise limit. In addition, we show that using\nsqueezed light, the shot noise limit can be overcome and the number of encoding\npossibilities increased. We discuss a possible application of our phase coding\nscheme for increasing the capacities of optical storage devices.",
