Ulawulo lwe-Laser PolarizationkwiTekhnoloji yeLaser
1, Inkcazo eSisiseko kunye neMilinganiselo ePhambili
Ulawulo lwe-laser polarization yiteknoloji ekhethekileyo yokulawula intsimi ye-optical eguqula, iguqula, izinzise, ​​kwaye ibone imeko ye-polarization yamaza okukhanya kwe-laser. Imeko ye-polarization ye-laser ibhekisa kwicala lokungcangcazela kwe-vector yentsimi yombane, kubandakanya i-linear polarization, i-circular polarization, kunye ne-elliptical polarization. Ukuguqulwa kwe-polarization state, ukuzinza kwe-polarization, kunye ne-high-speed polarization modulation kunokufezekiswa ngee-waveplates, ii-polarizers, kunye nezixhobo ze-phase modulation. Iimpawu ze-polarization zichaphazela ngokuthe ngqo ukuguqulwa kwe-nonlinear frequency, i-optical communication modulation, ukulinganiswa kwe-interferometric, kunye neziphumo ze-laser processing. Yiyunithi esebenzayo ebalulekileyo yeenkqubo ezahlukeneyo ze-laser echanekileyo. Ukuphendula ingxaki ye-product ye-polarization engazinzile okanye engahleliweyo yezinye ii-laser,ulawulo lwe-polarisationIyunithi inokuguqula naluphi na ulwahlulo lweziganeko lube yimeko yolwahlulo lweziganeko olujoliswe kulo kwaye itshintshe ulwahlulo ngesantya esiphezulu, ihlangabezana neemfuno zeenkqubo ezahlukeneyo zokuguqulwa kweenkqubo kunye neenkqubo ze-interferometric.

2, Imigaqo engundoqo kunye nokwakheka kwenkqubo
Umgaqo wobu buchwephesha usekelwe kwi-polarization yokukhanya evela kwi-spatial vibration orientation ye-light wave electric field: ii-polarizers zifumana i-polarization screening, zivumela kuphela ukukhanya oku-linearly polarized kwiindlela ezithile ukuba kudlule; Ii-wave plates zixhomekeke kwi-birefringence effect yeekristale ukuze zenze umahluko wesigaba esimiselweyo kwaye zifezekise ukuguqulwa kweemeko ezahlukeneyo ze-polarization; Isilawuli se-dynamic polarization silungisa i-birefringence ngokucinezela i-optical fiber kunye ne-electro-optic crystal, kwaye silungisa umahluko wesigaba ngexesha langempela ukuze sifezekise imeko ye-polarization eqhubekayo nehlengahlengiswayo. Ingabuyisela kwakhona i-birefringence engacwangciswanga ebangelwa kukuphazamiseka kwendalo kwi-optical fiber transmission kwaye ivale imeko ye-output polarization.
Inkqubo epheleleyo yokulawula i-laser polarization iqulathe i-polarizer/analyzer, i-phase delay waveplate, i-dynamic polarization controller, i-polarization detection module, kunye ne-polarization feedback locking unit.

3, Iiparameter eziphambili kunye nokuhlelwa kwemveliso
Iiparamitha zayo eziphambili ziquka umlinganiselo wokuphela kwe-polarization, ukuchaneka kokulibaziseka kwesigaba, isantya sempendulo ye-modulation, uluhlu lwamaza okusebenza, njl. Imveliso inokwahlulwa ibe lulawulo lwe-static polarization, ulawulo lwe-dynamic programmable polarization control, kunye nenkqubo yokutshixa i-polarization ngokwemo ye-modulation, ulawulo lwe-free space polarization kunye nolawulo lwe-fiber type polarization ngokwemo yesixhobo, kunye notshintsho lwe-polarization,uhlengahlengiso lwe-polarisation, uzinzo lwe-polarisation, kunye nohlalutyo kunye nokuchongwa kwe-polarisation ngokwemisebenzi.

4, Iingenelo, iingxaki kunye nesikhokelo sophuhliso
Iingenelo eziphambili zale teknoloji ziquka ukukwazi ukufezekisa utshintsho olungaqhelekanga lwe-polarization state, inkxaso yokutshintsha kwe-polarization ngesantya esiphezulu, ukuthintela i-optical path polarization drift, kunye nokuguquguquka okunamandla kwesixhobo. Nangona kunjalo, ikwanazo nemida efana nolwalamano oluqinileyo lwe-wave wave polarizers, ukuthambekela kwi-thermal birefringence kwiimeko zamandla aphezulu, umda ophantsi ophezulu wamandla okukhanya kwizixhobo ze-fiber optic, kunye ne-phase drift ebangelwa kukutshintsha kobushushu. Okwangoku, le teknoloji isetyenziswa kakhulu kunxibelelwano lwe-fiber optic, iinkqubo ze-optical ezingezizo ezilandelelanayo, i-precision interferometry, i-laser processing, uphando lwe-quantum optics kunye nezinye iimeko. Kwixesha elizayo, iya kuphuhlisela kwizixhobo zomda womonakalo ophezulu we-wideband, ulawulo lwe-electro-optical olukhawulezayo kakhulu, ulawulo lwe-photonic chip polarization oludibeneyo, uzinzo olukrelekrele lwe-closed-loop, kunye nokufunyanwa kwe-polarization epheleleyo edibeneyo.
