The invention discloses a two-dimensional array optical coupling module. The two-dimensional array optical coupling module comprises a ceramic substrate, a light receiving and transmitting chip array, a micro lens array, a driving unit array, optical fiber arrays and an optical fiber connector. According to the two-dimensional array optical coupling module of the invention, 45-degree reflecting surfaces are adopted as the coupling ends of the optical fiber arrays, and the coupling ends of the optical fiber arrays can be effectively coupled to the light receiving and transmitting chip array through micro lenses, and therefore, coupling efficiency is high, and the size of the module can be small, and packaging can be facilitated; proposed alignment and positioning methods are easy to realize, and industrial manufacture can be benefitted; the special-shaped ceramic substrate is adopted, so that the influence of optical path difference, on data transmission rate, can be decreased, and optical coupling efficiency can be improved; and the production cost of the two-dimensional array optical coupling module is relatively low compared to a polymer waveguide. With the two-dimensional array optical coupling module of the invention adopted, requirements for package miniaturization and high density of an parallel optical module can be satisfied; and the problems of high manufacturing cost, insufficient channels, difficulty in miniaturized package of the prior art can be solved. The two-dimensional array optical coupling module has a bright application prospect.
