Abstract
A tunable asymmetric interleaver constructed from two symmetric interleavers in series, wherein either or both of the individual symmetric interleavers exhibit a wavelength shifting ability. Advantageously, tunable asymmetric interleavers so constructed provide continuous tunable interleaving ratios from 0:100 to 50:50 to 100:0 and provide attractive upgrade paths for existing and future DWDM networks and applications.
