Implementing DWDM Lambda-Grids

, 2009
Unprecedented demand for ultrafast and dependable access to computing Grids contributes to the accelerating use of dense wavelength division multiplexing (DWDM) technology as a Lambda-Grid enabler. In the Lambda-Grid space, the DWDM infrastructure provisions dynamic lambdas or wavelengths of light ondemand to support terabyte and petabyte transmission ...

Rapid adiabatic couplers with arbitrary split ratios for broadband DWDM interleaver application. [PDF]

Nanophotonics
Abstract We experimentally demonstrate compact and broadband rapid adiabatic couplers (RACs) with arbitrary power split ratios, achieved through the combination of translational offset and waveguide width control. Fabricated RACs of four different target split ratios show power splitting within ±3 % of the design target over a 160 nm wavelength range ...
