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 7):
The optical source of  claim 1 , wherein the polarization beam coupler has a principal state of polarization and the first state of polarization and the second state of polarization are each rotated by 45 degrees relative to the principal state of polarization, and wherein the polarization beam coupler is arranged to combine the first optical signal and the second optical signal into two said composite optical signals each comprising a respective component of the first optical signal and a respective component of the second optical signal, and wherein the optical source comprises a further output, each said output arranged to output a respective one of the composite optical signals.
