Title: Optical mode couplers for multi-mode optical fibers

Abstract: An apparatus includes a first optical mode coupler having a spatial light modulator with a two-dimensional array of separately controllable optical phase modulators. The optical mode coupler is configurable to cause the spatial light modulator to couple a light source or light detector to an end-face of a multi-mode optical fiber via a plurality of light beams. Each of the light beams couples to a different one of optical modes in the multi-mode optical fiber.
