Optoelectronic array and method of making the same

摘要

An optoelectronic array and method for making same in which the device demonstrates efficient fill factor and focuses light upon an optoelectronic element close to the focal point of the light focusing element. The device comprises a substrate (12) supporting an optoelectronic element (14) , a microlens array (18), and a light transmissive layer (16) intermediate between the substrate (12) and the microlens array (18). The intermediate layer is of a thickness so that the spot size (5) formed by the light collected by the microlens is substantially smaller than the photosensitive or photosensitive area at the plane of the optoelectronic element. In alternate embodiments, the transmissive layer assists in achieving maximum fill factor. The method taught provides minimum alignment steps thereby providing a method of improved manufacturability.
