| description | A routing device with <inline-formula><tex-math notation="LaTeX">$N{{/ 2\,2}}\times {{2}}$</tex-math> </inline-formula> optical cross-connectors (OXCs) is based on a pair of <inline-formula><tex-math notation="LaTeX"> $N\times N$</tex-math></inline-formula> cyclic array waveguide gratings (AWGs) and multiple tunable fiber Bragg gratings (FBGs) to realize the dense wavelength-division multiplex (DWDM) channel configuration. A free spectral range (FSR) in the <inline-formula><tex-math notation="LaTeX">$N\times N$</tex-math></inline-formula> cyclic AWG is <inline-formula><tex-math notation="LaTeX">$N$</tex-math></inline-formula> channel spacing between two adjacent DWDM channels for each port pair. Planning every two-port pairs of the AWG is to effectively allocate the FSR for allowing the input of <inline-formula><tex-math notation="LaTeX">$N{{/ 2}}$</tex-math></inline-formula> separates the groups of DWDM channels. In this way, the DWDM channels in <inline-formula><tex-math notation="LaTeX">$N{{/ 2}}$</tex-math> </inline-formula> groups can be demultiplexed into output ports of the AWG with intervals of two channel spacings. A multiple tunable FBGs can be used to reflect the DWDM channels into one output port of the 2 × 2 OXC or be tuned into the interval of the FSR to make the DWDM channels pass through directly into the other output port. As a result, the proposed routing device costs little and offers more flexible scalability in a dynamic DWDM network. |
