Interleavers are designed on birefringent technology allowing linear-phase designs. Z-transform properties and digital filter design techniques are used for designing interleavers under a set of specifications. At a second level, a genetic algorithm optimization approach allows improving the interleaver design adjusting the minimum isolation, at both outputs, below -43 dB and the stop bandwidths to specific normalized values of ±0.15 and ±0.3, with zero dispersion at one output. Improvement of the interleaver order and dispersion below ±50 ps/nm at both outputs are also reported.14application/pdfeng© 2012 IEEEInterleaversBirefringent platesGenetic algorithms (GA)Finite impulse response (FIR) filtersFiber optic systemsresearch articleElectrónicaÓptica10.1109/JPHOT.2012.2235419open access1IEEE Photonics Journal5AR/0000011791
