Ukulawulwa Kokuhlukaniswa Kwe-Laser kubuchwepheshe be-Laser

Ukulawulwa Kokuhlukaniswa Kwe-Laserkubuchwepheshe be-Laser
1, Incazelo Eyisisekelo kanye Nezindinganiso Eziyinhloko
Ukulawulwa kwe-laser polarization ubuchwepheshe obukhethekile bokulawula insimu ye-optical obuguqula, buguqule, buzinze, futhi bubone isimo se-polarization samaza okukhanya kwe-laser. Isimo se-polarization se-laser sibhekisela ekuqondeni kokudlidliza kwe-vector yensimu kagesi, okuhlanganisa i-linear polarization, i-circular polarization, kanye ne-elliptical polarization. Ukuguqulwa kwesimo se-polarization, ukuzinza kwe-polarization, kanye nokuguqulwa kwe-polarization okusheshayo kungatholakala ngama-waveplates, ama-polarizers, kanye namadivayisi we-phase modulation. Izici ze-polarization zithinta ngqo ukuguqulwa kwemvamisa engeyona i-linear, ukuguqulwa kwe-optical communication, ukulinganiswa kwe-interferometric, kanye nemiphumela yokucubungula i-laser. Kuyiyunithi yokusebenza ebalulekile yezinhlelo ezahlukene ze-laser ezinembile. Ukuphendula inkinga yokukhishwa kwe-polarization okungazinzile noma okungahleliwe kwamanye ama-laser,ukulawulwa kokwehlukanaiyunithi ingaguqula noma yikuphi ukuhlukaniswa kwezehlakalo kube yisimo sokuhlukaniswa okuqondiwe futhi ishintshe ngokuguquguqukayo ukuhlukaniswa ngesivinini esikhulu, ihlangabezane nezidingo zezinhlelo ezahlukene zokuguquguquka kanye nezinhlelo ze-interferometric.

2, Izimiso eziyinhloko kanye nokwakheka kohlelo
Isimiso esingokoqobo salobu buchwepheshe sisekelwe ekuhlukanisweni kokukhanya okuvela ekuqondisweni kokudlidliza kwendawo kwensimu kagesi yamagagasi okukhanya: ama-polarizers afinyelela ukuhlolwa kwe-polarize, okuvumela ukukhanya okulinganiselwe kuphela eziqondisweni ezithile ukuthi kudlule; Ama-wave plate athembele kumphumela we-birefringence wamakristalu ukwethula umehluko wesigaba ohleliwe futhi afinyelele ukuguqulwa kwezimo ezahlukene ze-polarization; Isilawuli se-dynamic polarization silungisa i-birefringence ngokucindezela i-optical fiber kanye ne-electro-optic crystal, futhi silungisa umehluko wesigaba ngesikhathi sangempela ukuze sifinyelele isimo se-polarization esiqhubekayo nesilungisekayo. Singakwazi futhi ukukhokhela i-birefringence engahleliwe ebangelwa ukuphazamiseka kwemvelo ekudlulisweni kwe-optical fiber futhi sivale isimo se-polarization esiphumayo.
Uhlelo oluphelele lokulawula i-laser polarization luqukethe i-polarizer/analyzer, i-phase delay waveplate, isilawuli se-dynamic polarization, i-polarization detection module, kanye neyunithi yokukhiya impendulo ye-polarization.

3, Amapharamitha ayisihluthulelo kanye nokuhlukaniswa komkhiqizo
Amapharamitha ayo ayinhloko afaka isilinganiso sokuphela kwe-polarization, ukunemba kokulibaziseka kwesigaba, isivinini sokuphendula kwe-modulation, ububanzi bobude be-wavelength obusebenzayo, njll. Umkhiqizo ungahlukaniswa ngokulawulwa kwe-static polarization, ukulawulwa kwe-dynamic programmable polarization control, kanye nohlelo lokukhiya kwe-polarization ngokwemodi ye-modulation, ukulawulwa kwe-free space polarization kanye nokulawulwa kwe-fiber type polarization ngokwehlobo lwedivayisi, kanye nokuguqulwa kwe-polarization,ukuguqulwa kwe-polarization, ukuzinza kwe-polarization, kanye nokuhlaziywa kwe-polarization kanye nokutholakala kwayo ngokwemisebenzi.

4, Izinzuzo, ukungalungi kanye nesiqondiso sentuthuko
Izinzuzo eziyinhloko zalobu buchwepheshe zifaka phakathi ikhono lokufeza ukuguqulwa kwesimo se-polarization okungahleliwe, ukwesekwa kokushintsha kwe-polarization ngesivinini esikhulu, ukucindezela i-optical path polarization drift, kanye nokuzivumelanisa nezimo okuqinile kwedivayisi. Kodwa-ke, futhi inemikhawulo efana nokuhlangana kwe-wavelength okuqinile kwama-polarizers e-wave plate, ukuthambekela ku-thermal birefringence ezimweni zamandla aphezulu, umkhawulo ophansi wamandla okukhanya wamadivayisi e-fiber optic, kanye ne-phase drift okubangelwa izinguquko zokushisa. Njengamanje, lobu buchwepheshe busetshenziswe kabanzi ekuxhumaneni kwe-fiber optic, izinhlelo ze-optical ezingezona eziqondile, i-interferometry enembile, ukucubungula nge-laser, ucwaningo lwe-quantum optics kanye nezinye izimo. Esikhathini esizayo, buzothuthukela kumadivayisi omkhawulo womonakalo omkhulu we-wideband, ukulawulwa kwe-electro-optical ngesivinini esikhulu kakhulu, ukulawulwa kwe-photonic chip polarization okuhlanganisiwe, ukuzinza okuhlakaniphile kwe-closed-loop, kanye nokutholwa kwe-polarization okugcwele okuhlanganisiwe.
