System design and performance of reconfigurable and simultaneous 2D multiple-plane WDM optical interconnects

摘要

A system design for reconfigurable and simultaneous 2D multiple plane WDM optical interconnects has been investigated. Device characteristics such as detector responsivity shape, efficiency, and complexity affect the design requirements for wavelength separation and channel power. With decreasing wavelength separation, increased optical crosstalk and signal power loss result in performance penalties most notably for the middle wavelength channels. When signal power loss and optical crosstalk from the detection of undesired channels are evaluated, it is found that wavelength channel spacing down to 10 nm can be tolerated for the specific detector responsivity shape and efficiency attainable from currently available devices.
