Systems and methods, e.g., optical apparatuses, for digital optical information storage systems that improve the speed, signal to noise, controllability, and data storage density for fluorescent and reflective multilayer optical data storage media. The systems and methods include an optical system for a reading beam of a data channel from a moving single or multi-layer or otherwise 3-dimensional optical information storage medium that comprises at least one optical element characterized by restricting the field of view (FOV) of the reading beam on an associated image plane to 0.3 to 2 Airy disk diameters in a first direction.

Systems and methods for increasing data rate and storage density in 3-dimensional optical data storage media

An optical information storage medium includes a substrate and a multilayer polymeric film. The multilayer polymeric film has a first surface and an opposite second surface that extend the length of the multilayer polymeric film. The second surface is adhered to a surface of the substrate. The multilayer polymeric film includes a plurality of coextruded alternating polymeric active data storage layers and polymeric buffer layers.

Optical information storage medium

An optical information storage medium includes a multilayer film that includes a plurality of extruded alternating active data storage layers and buffer layers, which separate the active data storage layers. The active data storage layers and buffer layers have thicknesses that allow the active data storage layers to be writable by non-linear or threshold writing processes to define data voxels within the active data storage layers that are readable by an optical reading device.

The active data storage layers and buffer layers have thicknesses that allow the active data storage layers to be writable by permanent or reversible one- or multiphoton, linear, nonlinear, or threshold optical writing processes to define data voxels within the active data storage layers that are readable by an optical reading device.

A polymer film laser is provided that comprises a plurality of extruded polymer layers. The plurality of extruded polymer layers comprises a plurality of alternating dielectric layers of a first polymer material having a first refractive index and a second polymer material having second refractive index different than the first refractive index.

An integrated circuit device (11) is tested by directing a laser beam (19) onto an electrochromic member (17) in close proximity to a conductor (13) of the integrated circuit. Reflected laser light is directed to a detector (21) which converts it to an electrical signal for display by a lock-in amplifier (25). The display characterizes the voltage on the conductor (17) and thereby permits diagnosis of the operation of the integrated circuit (11).
