Optical waveguide array imaging devices have a darkened surface layer in the cladding portion. The imaging devices of the invention have high contrast which is generally independent of pathlength. A method for contrast enhancement in such arrays is disclosed.

Waveguide arrays and method for contrast enhancement

An FOFP has a darkened surface layer in the cladding portion to reduce cross-talk. One embodiment has an intagliated surface with darkened cavity walls. Darkening is achieved on a finished piece without further reworking. The surface is substantially free of fluorescence and is substantially non-conductive.

Waveguide array and method for contrast enhancement

Fiber composites, particularly for imaging, easy to manufacture even with great cross-sectional area, in which fibers are in a peak-to-valley relation with abutting pairs of fibers throughout.

Method for making multifiber assembly from primitive tiles

The photorefractive effect results in a change in the refractive index of bulk chalcogenide glass when it is exposed to certain wavelengths of light, in particular, sub-band-gap light. The effect results in a variety of device structures including a fiber optic faceplate; an optical waveguide; a fiber tap; a lens and a Bragg grating. Methods for fabricating the various devices are described.

An intgeral printhead includes a single fiber optic faceplate substrate to which are connected light emitting diode arrays, driver circuits for selectively controlling the energization of the light emitting diodes and interconnecting conductive lines all disposed on the same fiber optic faceplate substrate which thereby provides the optical lens system for the light emitting diodes and a supporting substrate to which the active components are mounted and electrically interconnected by the conductive lines.
