Title:
PHOTOELECTRIC CONVERSION ELEMENT ARRAY, ITS INTEGRATED DEVICE, THEIR PACKAGING STRUCTURE, AND OPTICAL INFORMATION PROCESSOR
Document Type and Number:
WIPO Patent Application WO/2005/117146
Kind Code:
A1
Abstract:
A photoelectric conversion element array comprising a plurality of photoelectric conversion elements (a light emitting element (4), a light receiving element (5)) arranged in array wherein the photoelectric conversion elements (4, 5) are arranged alternately at different positions so that every other element is positioned on the same line in the array direction. In the packaging structure of the photoelectric conversion element array, a light emitting element array and a light receiving element array of the photoelectric conversion element array are arranged oppositely to an interposer substrate (9) and these arrays are mounted on the interposer substrate (9) through an external connection terminal (7). An optical information processor (1) comprises the photoelectric conversion element array, and an optical waveguide (3) opposing each element of the photoelectric conversion element array. The photoelectric conversion element capable of high density integration of optical wiring, reduction in optical interference and crosstalk due to the photoelectric conversion element, and efficient propagation of light can thereby be provided. Its integrated device, their packaging structure and an optical information processor can also be provided.
