1. A mode coupling connector system comprising:
a first fiber connector comprising a first ferrule having a first fiber receiving hole;
a second fiber connector comprising a second ferrule having a second fiber receiving hole, wherein
the first fiber connector and the second fiber connector are coupled to a coupler housing; the first fiber connector is positioned in a first receiving cavity of the coupler housing and the second fiber connector is positioned in a second receiving cavity of the coupler housing;
the first fiber receiving hole extends from an outer end of the first ferrule to an inner end of the first ferrule;
the second fiber receiving hole extends from an outer end of the second ferrule to an inner end of the second ferrule; the first fiber receiving hole and the second fiber receiving hole are in axial alignment; and
a mode coupling plate comprising a phase mask array of a plurality of phase masks, wherein the mode coupling plate is positioned in a plate receiving hole of the coupler housing between the first receiving cavity and the second receiving cavity and at least two phase masks of the phase mask array are circumscribed by the fiber receiving hole of both the first fiber connector and the second fiber connector.
