Short-length storage of intense optical pulses in solid by adiabatic passage
2009
We propose a novel scheme of storage of intense pulses which allows a significant reduction of the storage length with respect to standard schemes. This scheme is particularly adapted to store optical information in media with fast relaxations.
Three-dimensional superresolution by annular binary filters
1999
We present a new family of annular binary filters for improving the three-dimensional resolving power of optical systems. The filters, whose most important feature is their simplicity, permit to achieve a significant reduction, both in the transverse and in the axial direction, of the central lobe width of the irradiance point spread function of the system. The filters can be used for applications such as optical data storage or confocal scanning microscopy.
Reversible Digital And Holographic Optical Storafe In Polymeric Liquid Crystals (PLC)
1987
A new reversible optical storage technique based on azo dye containing liquid crystalline polymers and copolymers is described. Monodomain films of the polymers were used as storage medium. Digital and holographic information was stored and reconstructed. The stored information can be erased and the writing process is repeatable. The storage process is explained in terms of a transcis isomerization of the mesogen inducing local director field distortions.
