Objective
The heart of the system will be an optical parametric oscillator (OPO) driven by a diode-pumped solid-state laser. The output of the OPO will in turn be frequency doubled in a broadband quasi-phase-matched (QPM) device. Around the centre wavelength the device will be able to quickly select at random anyone of hundreds of discrete optical frequencies, each used to write or read a hologram (a page of information of the order of 1 Mbyte). Combined with spatial multiplexing, where the device optically or mechanically addresses consecutive volumes, storage of several Gbytes of information will be possible.
The project concerns a coherent, frequency multiplexed light source with an absolute frequency reference and the ability of fast random switching between a set of discrete frequencies. Such a source would have great importance for future optical mass information storage devices, as frequency multiplexing of optical holograms offers potential advantages over the more commonly proposed angular multiplexing, and the related components have the potential for a high degree of integration and low cost.
