The paper presents the economical design of the Optical Matrix to Vector Multiplier (OMVM) for optical education. This OMVM has a three-layer structure: input optical waveguides, a two-dimensional aperture array and output optical waveguides. It can be manufactured by students in university labs without expensive lithography equipment. The OMVM can be applied for hardware realization of artificial neural networks, integral transform calculators, optical signal processors, etc. The process of assembling, testing and implementation of the OMVMs helps students to improve knowledge and skills in optics, signal processing, artificial intelligence, and mathematics.
