Abstract
An optical de-interleaver for de-interleaving light beams of odd and even channel signals having channel spacing S into light beams of odd channel signals having channel spacing S and light beams of even channel signals having channel spacing S is provided which has only one polarization interferometer and one optical dispersion compersator. A 50/100 GHz de-interleaver and a 50/200 GHz de-interleaver with high isolation and dispersion compensation are provided by applying this unique arrangement. The optical de-interleaver has a 0.5 dB passband width of about 30 GHz and a −25 dB isolation stopband width of about 30 GHz.
