ʻO nā nalu māmā ma kahi ākea (e like me nā hawewe electromagnetic o nā alapine ʻē aʻe) he mau nalu shear, a ʻo ke kuhikuhi o ka haʻalulu o kāna mau uila a me ka magnetic he mau ʻano hiki ke kuhikuhi ʻia i ka pauku kea e kū pono ana i ke kuhikuhi o ka hoʻolaha ʻana, ʻo ia ka waiwai polarization. o ka malamalama. He waiwai koʻikoʻi ka polarization ma nā ʻano o ka kamaʻilio optical coherent, ʻike ʻenehana, biomedicine, ʻike mamao honua, pūʻali koa hou, mokulele a me ka moana.

Ma ke ʻano, i mea e hoʻokele maikaʻi ai, ua hoʻomohala nā mea ola he nui i nā ʻōnaehana ʻike e hiki ke hoʻokaʻawale i ka polarization o ka mālamalama. No ka laʻana, he ʻelima maka o ka nalo (ʻekolu maka hoʻokahi, ʻelua maka hui pū), aia i kēlā me kēia me 6,300 mau maka liʻiliʻi, e kōkua ana i ka nalo e loaʻa i kahi palapala o ka polarization o ka mālamalama ma nā ʻaoʻao āpau o ka lewa. Hiki i ka nalo ke hoʻohana i ka palapala ʻāina polarization e huli a alakaʻi pololei i kona ʻano ponoʻī i nā pua i loaʻa iā ia. ʻAʻohe kino kino o ke kanaka e like me ka nalo e ʻike i ka polarization o ka mālamalama, a pono e hoʻohana i nā mea hana hana e ʻike a hoʻoponopono i ka polarization o ka mālamalama. ʻO kahi hiʻohiʻona maʻamau ka hoʻohana ʻana i nā aniani polarizing e kuhikuhi i ka mālamalama mai nā kiʻi like ʻole i ka maka hema a me ka ʻākau i nā polarization perpendicular, ʻo ia ke kumu o nā kiʻiʻoniʻoni 3D i ka hale kiʻiʻoniʻoni.

ʻO ka hoʻomohala ʻana i nā mea hoʻokele polarization optical kiʻekiʻe ke kī e hoʻomohala i ka ʻenehana noi māmā polarized. Aia nā mea hoʻomalu polarization maʻamau i ka polarization state generator, scrambler, polarization analyzer, polarization controller, etc.

Lawe anakamaʻilio ʻike makae like me ka laʻana, alakaʻi ʻia e ke koi no ka hoʻouna ʻana i ka ʻikepili nui i nā kikowaena data, lōʻihi lōʻihi coherentopticalKe hoʻolaha mālie nei ka ʻenehana kamaʻilio i nā noi pili pili pōkole e pili nui ana i ke kumu kūʻai a me ka hoʻohana ʻana i ka ikehu, a hiki i ka hoʻohana ʻana i ka ʻenehana manipulation polarization hiki ke hoʻemi pono i ke kumukūʻai a me ka hoʻohana ʻana i ka mana o nā ʻōnaehana kamaʻilio optical coherent pōkole. Eia nō naʻe, i kēia manawa, ʻike nui ʻia ka mana polarization e nā ʻāpana optical discrete, kahi e kaohi nui ai i ka hoʻomaikaʻi ʻana o ka hana a me ka hōʻemi ʻana i ke kumukūʻai. Me ka hoʻomohala wikiwiki ʻana o ka ʻenehana hoʻohui optoelectronic, ka hoʻohui ʻana a me ka chip he mau ʻano koʻikoʻi i ka hoʻomohala ʻana o nā mea mana o ka optical polarization.
Eia nō naʻe, ʻo nā alakaʻi nalu optical i hoʻomākaukau ʻia i loko o nā kristal lithium niobate kuʻuna i nā hemahema o ka liʻiliʻi refractive index ʻokoʻa a me ka hiki ke hoʻopaʻa paʻa i ka māla optical. Ma ka lima hoʻokahi, nui ka nui o ka mīkini, a paʻakikī ke hoʻokō i nā pono hoʻomohala o ka hoʻohui. Ma ka ʻaoʻao ʻē aʻe, nāwaliwali ka pilina electrooptical, a ʻoi aku ka kiʻekiʻe o ka uila uila o ka mea.

I nā makahiki i hala iho nei,nā mea paʻi kiʻima muli o ka lithium niobate ua holomua nā mea kiʻi ʻoniʻoni lahilahi, e loaʻa ana nā wikiwiki kiʻekiʻe a me nā haʻahaʻa haʻahaʻa haʻahaʻa ma mua o nā kuʻuna.nā mea paʻi kiʻi lithium niobate, no laila makemake ʻia lākou e ka ʻoihana. Ma ka noiʻi hou, ua ʻike ʻia ka puʻupuʻu hoʻomalu polarization optical i ka lithium niobate thin film photonic integration platform, me ka polarization generator, scrambler, polarization analyzer, polarization controller a me nā hana nui ʻē aʻe. ʻO nā palena nui o kēia mau chips, e like me ka wikiwiki o ka hanauna polarization, polarization extinction ratio, polarization perturbation speed, a me ke ana wikiwiki, ua hoʻonohonoho i nā moʻolelo honua hou, a ua hōʻike i ka hana maikaʻi loa i ka wikiwiki kiʻekiʻe, ke kumu kūʻai haʻahaʻa, ʻaʻohe parasitic modulation nalowale, a haʻahaʻa. uila uila. ʻO nā hualoaʻa noiʻi no ka manawa mua e ʻike i kahi moʻo o ka hana kiʻekiʻelithium niobateʻO nā mea hoʻokele polarization optical kiʻi ʻoniʻoni, i haku ʻia me ʻelua mau ʻāpana kumu: 1. Polarization rotation/splitter, 2. Mach-zindel interferometer (wehewehe >), e like me ka mea i hōʻike ʻia ma ke Kiʻi 1.
