摘要： Bidirectional isolating devices including non-reciprocal rotators (i.e. Faraday rotators) and wavelength selective reciprocal polarization rotators are disclosed. Each wavelength selective rotator behaves like a half-wave retarder in a first frequency range and behaves like a full-wave retarder in a second frequency range, according to a substantially periodic transfer function. The rotation has a predetermined number of birefringent elements (e.g. waveplates), the thickness and the orientation of which are chosen so as to obtain a transition between the half-wave retarder behavior and the full-wave retarder behavior in a frequency range lower than or equal to 40% of the period of the transfer function. In order to satisfy such a requirement, a relatively high number of birefringent elements is required, i.e. at least the five birefringent elements. Advantageously, the isolating device may comply with any allocation scheme for the opposite propagating signals.

摘要： An optical transmission system having optical fibres having chromatic dispersion of alternate sign arranged in an optical path in accordance with a dispersion map appropriate for the transmission of dispersion managed solitons at a wavelength λc. The transmission system has a transmission station and a receiver station connected to the optical path.

At least one wavelength conversion device such as a phase conjugation device located along the optical path alters the wavelength of the first pulse of wavelength λ1 in such a way as to obtain a second pulse of wavelength λ2, such that λ2 is on the opposite side from λ1 with respect to λc.
