Multi-mode fiber coarse WDM grating router using broadband add/drop filters for wavelength re-use
For single mode fiber (SMF) applications the arrayed waveguide grating router (AWG) provides passive wavelength routing with spectral channels being used more than once in the routing table to achieve full NxN interconnection with only N wavelengths[l]. AWGs cannot be used with MMF due to the excessive losses in coupling from MMF to single mode waveguides. We report the development of a wavelength router (NxN wavelength multiplexer) for use in h and lF based optical networks. The device uses a blazed diffraction grating and broadband add/drop filters to provide wavelength re-use thus enabling fully non-blocking NxN interconnection with only N wavelengths. Initial experimental results using 3 inputs and 3 outputs are presented.
