Polarization Synthesizer/Analyzer – PolaFlex™

ThePSY-201 isadeterministicpolarizationcontroller thatcangenerateandmaintainanystateofpolarization (SOP), regardlessof the inputSOP. It combinesGeneralPhotonics’ patented polarization controller, in-line polarimeter, and control algorithm into an instrument that functions as both a polarization state generator and a polarization analyzer.ThegeneratedSOPandthecorrespondingPoincaréSphererepresentationcanbedisplayedonacomputerscreenviaUSBinterface.TheoutputSOPcanbespecifiedbyinputtingStokesparametersusingthefrontpanelkeypadorbymanuallytuningtheSOPtoreachaspecificpointonthePoincarésphereortoreachanoptimumvalueofapolarization-dependentmetric.OnceadesiredoutputSOP is found, the instrumentcanautomaticallymaintain thisSOPagainst inputSOPfluctuations.Anotherattractivefeatureisthattheusercangenerateanyof6distinctSOPs(0°, 90°, ± 45°,RHCandLHC) forMuellermatrixcalculations,orselectanyof the6statesat the touchofabutton.Furthermore, the instrumentcangenerateseveralpreprogrammedSOPtraces
