Abstract

A receiver for multiple groups of modes comprising a beam splitter (21) for receiving an incoming optical signal from a graded index rod (19). The incoming optical signal includes low mode groups (33) and high mode groups (31). The beam splitter (21) transmits a transmitted portion of the incoming signal toward a graded index rod (23) and reflects a reflected portion of the incoming signal to a detector (27). The graded index rod (23) substantially separates the low mode group (33) from the high mode group (31) in the transmitted portion of the signal and provides a separated signal in the form of the low mode group (33) to a detector (25).
