摘要： Disclosed is a novel multi-layered optical recording media and system for recording and reproducing information data. The multi-layered topical recording media has M information storage decks, and each information storage deck has N information storage layers, and each information storage layer has a pair of information storage structures. Each paired information storage structure has a characteristic wavelength and polarization state, and from which recorded information can be read by a laser beam having similar wavelength and polarization-state characteristics. In the illustrative embodiment, the multi-layered optical recording media of the present invention has MxNx2 information storage layers which can be read using only N laser lines (i.e. spectral components), thereby providing a 2M-fold increase in information storage capacity over prior art systems. The information storage and retrieval system of the present invention is completely backward compatible to allow for the reading of conventional CD-ROM devices.

摘要： A method is provided for fabricating composite nonlinear optical (NLO) organic films that are suited for use in NLO device applications. The highly NLO properties of these films arise from the vector alignment of ‘guest’ NLO molecules in a self-ordered nano-structured liquid crystal ‘host’ film. Field-poling is used to remove the centro-symmetry. The ‘guest’ concentration is increased by film processing to incorporate oriented nonlinear nano-crystallites to increase nonlinearity. NLO devices based on such films are of low cost and permit fast switching in a compact device format.

摘要： A light polarizer includes a plurality of discrete layers of birefringent film disposed in superposed relation on a transparent substrate. The planar components of the optic axes of each successive one of the discrete layers are angularly offset relative each preceding one of the discrete layers by a predetermined angle in one or either a positive or negative direction to provide the light polarizer with selectivity for either right-handed circularly polarized (RHCP) or left-handed circularly polarized (LHCP) incident light. In another aspect of the invention, the layers are of quarter-wave thickness having planar components orthogonally offset to provide selectivity for either right or left linearly polarized light. In a still further aspect of the invention, an optically isotropic layer of quarter-wave thickness is disposed between adjacent birefringent quarter-wave plates.

摘要： A coherent laser beam having a possibly non-uniform spatial intensity distribution is transformed into an incoherent light beam having a substantially uniform spatial intensity distribution by homogenizing the laser beam with a light tunnel (a transparent light passageway having flat internally reflective side surfaces). It has been determined that when the cross-section of the tunnel is a polygon (as preferred) and the sides of the tunnel are all parallel to the axis of the tunnel (as preferred), the laser light at the exit of the light tunnel (or alternatively at any image plane with respect thereto) will have a substantially uniform intensity distribution and will be incoherent only when the aspect ratio of the tunnel (length divided by width) equals or exceeds the contangent of the input beam divergence angle .theta. and whenW.sub.min =L.sub.coh (R+(1+R.sup.2).sup.1/2)>2RL.sub.coh,where W.sub.min is the minimum required width for the light tunnel, L.sub.coh is the effective coherence length of the laser light being homogenized and R is the chosen aspect ratio for the light tunnel.
