Planar integration method of crossover broadband network using acute prism array

摘要

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a planar integration method of a free space optical system and more particularly to a planar integration method of a crossover switching network that has been implemented in a large scale by spatially arranging individual optical elements such as mirrors, The optical system of a conventional crossover distribution network is mainly composed of a mirror, a lens, a beam splitter prism, and the like in general. , Which results in a large overall size and difficulty in achieving an alignment accuracy of less than 1 m for the optical components for the construction and maintaining the alignment after construction It has a very difficult disadvantage.;Therefore, an optical crossover distribution network that can be used in this switching network can be realized only if the alignment accuracy of 1 m or less and the optical system can be claimed at a smaller scale.;The object of the present invention is to provide a planar integration method of a crossover broadband network with high alignment and wafer scale based on the planar integration technique of an optical system using lithography technology for manufacturing an electronic integrated circuit in order to satisfy the conventional requirements And more particularly to provide a planar integration method of a crossover broadband network in which an optical signal connection characteristic of a crossover interconnect network is sketched by using an acute angle prismarray.
