摘要： A photorefractive device (100) and method of manufacture are disclosed. The device (100) comprises a layered structure in which one or more polymer layers (110) are interposed between a photorefractive material (106) and at least one transparent electrode layer (104). One or more electrolytes are dispersed into the one or more polymer layers (110). When a bias is applied to the device (100), the device (100) exhibits an increase in signal efficiency compared to a similar device without electrolyte. Both grating decay time and grating response time are greatly reduced by dispersing electrolytes into one or more polymer layers in the photorefractive device. The grating decay time can be adjusted by dispersing different kinds of the electrolytes and/or different concentration of the electrolytes, which can be fitted into all kinds of applications with different requirements for grating response and decay time.

摘要： An optical memory medium (2) comprises cores (21) constituting flat optical waveguides and clads (22) holding the cores between them, and has, at the interface of a core (21) and a clad (22) or in a core (21), a data image (203) in which data is recorded as a scattering factor and a pair of positioning marks (201, 202) that are scattering factors respectively needed for positioning. A reading beam (103) advances through a core (21) in an expanding manner, is scattered by and interfered with a data image (203), and data is reproduced from a data reproduction beam (1031) produced by it. A pair of positioning beams (101, 102) are shone into a core (21) with an offset in opposite directions with respect to the reading beam (103) and in the thickness direction of a core (21), and respectively scattered and interfered at a pair of positioning marks (201, 202). The incident position at a core (21) in its thickness direction of a beam emitted from a light source (11) is controlled based on the respective intensities of a pair of positioning mark beams (1011, 1021) thus produced.
