Transverse lightwave circuits in microstructured optical fibers: waveguides.
Novel class of microstructured optical fiber couplers is introduced that operates by resonant, rather than proximity, energy transfer via transverse lightguides built into a fiber cross-section. Such a design allows unlimited spatial separation between interacting fibers which, in turn, eliminates inter-core crosstalk via proximity coupling. Controllable energy transfer between fiber cores is then achieved by localized and highly directional transmission through a transverse lightguide. Main advantage of this coupling scheme is its inherent scalability as additional fiber cores could be integrated into the existing fiber cross-section simply by placing them far enough from the existing circuitry to avoid proximity crosstalk, and then making the necessary inter-core connections with transverse light "wires" - in a direct analogy with an on chip electronics integration.
