Abstract

Star couplers are general fan-in/fan-out devices with each individual input furnishing equal light to all outputs. After a brief look at the thermodynamics of star couplers, we describe three distinct types of holographic star couplers: (1) a single-mode coupler with predictable loss, (2) a lossless multimode coupler, and (3) an agile star coupler that reconfigures according to our desire.
