Title:
CYCLIC WAVELENGTH ROUTER
Document Type and Number:
WIPO Patent Application WO2003047305
Kind Code:
A3
Abstract:
The invention concerns a wavelength or optical frequency cyclic wavelength router. The invention is useful for producing passive or active routers, cross-connect arrays, or wavelength-selective add-drop components. The invention is characterized in that a cyclic router with N input ports and N output ports can be produced from a non-cyclic router with diffraction or waveguide grating. Said cyclic router is single, and is associated with N output ports and 2N input ports with particular coupling of the input ports in pairs, or it is dual and associated with N output ports and N input ports split into 2N images in the output plane. The grating can operate in any single order with wide free spectral range and with high efficiency.
