Abstract
The authors derive an analytical solution for crosstalk-induced penalty in wavelength routers with consideration of the extinction ratio. Both theoretical and experimental results suggest that the extinction ratio can induce a system penalty and should be kept to at least ~15 dB to maintain the penalty below 1 dB for a total crosstalk level of ~–23 dB.Keywords
