Interface loss, diffraction loss, and physical sizes of arrayed-waveguide AWG devices 10, such as AWG routers, are reduced via use of an array 12 of asymmetric waveguide couplers 20 that is inserted between arrayed waveguides 13. The asymmetric waveguide couplers 20 operate to couple leaked optical...
