Abstract:
An optical source comprises a first laser arranged to generate a first optical signal having a first state of polarization (SOP) and a first optical frequency; a second laser arranged to generate a second optical signal having a second SOP, substantially orthogonal to the first SOP, and having a second optical frequency, different from the first optical frequency by a preselected frequency difference; a polarisation beam coupler arranged to combine the first optical signal and the second optical signal into a composite optical signal comprising both the first optical signal and the second optical signal having said substantially orthogonal SOPs; and an output arranged to output the composite optical signal.

Claim (Index 8):
A communications network optical apparatus comprising:\n the optical source of  claim 1 ; a polarization selective optical filter arranged to receive a said composite optical signal generated by the optical source and arranged to transmit a portion of the composite optical signal having a preselected state of polarization; and an optical device arranged to operate at the preselected state of polarization and arranged to receive said portion of the composite optical signal transmitted by the polarization selective optical filter.
