Hōʻike pōkole o Lithium Niobate Crystal a me kāna mau noi - Māhele 7: ʻO ka Dielectric Superlattice o LN Crystal

Ma 1962, Armstrong et al.ʻO ka manaʻo mua o ka QPM (Quasi-phase-match), e hoʻohana ana i ka vector lattice inverted i hāʻawi ʻia e superlattice e uku.pua like ʻole ke kaʻina hana parametric optical.ʻO ke kuhikuhi polarization o ferroelectricshoʻohuli manaʻos ka helu polarization nonlinear χ2. Hiki ke hoʻokō ʻia ka QPM ma o ka hoʻomākaukau ʻana i nā hale ferroelectric domain me nā kuhikuhi polarization periodic i nā kino ferroelectric., me ka lithium niobate, lithium tantalate, aKTPnā kristal.ʻO ke aniani LN kaākea loahoʻohana ʻiamea waiwaima keia kahua.

I ka makahiki 1969, ua manaʻo ʻo Camlibel i ka ferroelectric domain oLNHiki ke hoʻohuli ʻia nā kristal ferroelectric ʻē aʻe ma o ka hoʻohana ʻana i ke kahua uila uila kiʻekiʻe ma luna o 30 kV/mm.Eia nō naʻe, hiki i ke kahua uila kiʻekiʻe ke hoʻopaʻa maʻalahi i ke aniani.I kēlā manawa, paʻakikī ka hoʻomākaukau ʻana i nā hale electrode maikaʻi a hoʻokele pono i ke kaʻina hoʻohuli polarization domain.Mai ia manawa, ua hana ʻia nā hoʻāʻo e kūkulu i ka ʻōnaehana multi-domain ma ke ʻano o ka lamination oLNnā kristal i nā ʻaoʻao polarization like ʻole, akā ua kaupalena ʻia ka helu o nā chips i hiki ke hoʻomaopopo ʻia.I ka makahiki 1980, ʻo Feng et al.loaʻa nā kristal me ka hoʻolālā domain polarization periodic ma ke ʻano o ka ulu eccentric ma ka hoʻokaʻawale ʻana i ke kikowaena rotation crystal a me ke kahua wela axisy-symmetric center, a ʻike i ka puka pālua pālua o 1.06 μm laser, ka mea i hōʻoia i kaQPMmanaʻo.Akā paʻakikī kēia ʻano hana i ka hoʻokele maikaʻi ʻana o ka hoʻolālā periodic.I ka makahiki 1993, ʻo Yamada et al.Ua hoʻoholo maikaʻi ʻo ia i ke kaʻina hoʻohuli polarization domain periodic ma o ka hoʻohui ʻana i ke kaʻina hana lithography semiconductor me ke ʻano kahua uila.Ua lilo mālie ke ʻano hana polarization i hoʻohana ʻia i ka ʻenehana hoʻomākaukau nui o ka poled periodicLNaniani.I kēia manawa, poled ka periodic poledLNUa kūʻai ʻia ke aniani a hiki i kona mānoanoabeʻoi aku ma mua o 5 mm.

ʻO ka hoʻohana mua ʻana o ka poled periodicLNManaʻo nui ʻia ka kristal no ka hoʻololi pinepine ʻana i ka laser.Ma mua o 1989, Ming et al.manaʻo ʻia ka manaʻo o nā superlattices dielectric e pili ana i nā superlattices i kūkulu ʻia mai nā kikowaena ferroelectric oLNnā kristal.ʻO ka lattice inverted o ka superlattice e komo i ka hoʻoulu a me ka hoʻolaha ʻana o nā nalu māmā a me nā kani.I ka makahiki 1990, ʻo Feng lāua ʻo Zhu et al.manaʻo ʻia ka manaʻo o ka hoʻohālikelike like ʻana.Ma 1995, Zhu et al.hoʻomākaukau ʻia nā superlattices quasi-periodic dielectric e ka ʻenehana polarization wela o ka lumi.Ma 1997, ua hoʻokō ʻia ka hōʻoia hoʻokolohua, a me ka hoʻohui maikaʻi ʻana o ʻelua kaʻina hana parametric optical-Ua ʻike ʻia ka pālua pinepine a me ka hōʻuluʻulu pinepine ʻana i kahi superlattice quasi-periodic, no laila e loaʻa ai ka maikaʻi o ka laser triple frequency double no ka manawa mua.Ma 2001, Liu et al.ua hoʻolālā i kahi hoʻolālā e ʻike i ka laser ʻekolu kala e pili ana i ka hoʻohālikelike quasi-phase.I ka makahiki 2004, ua ʻike ʻo Zhu et al i ka hoʻolālā superlattice optical o ka hoʻopuka laser lōʻihi-nui a me kāna noi ʻana i nā lasers solid-state.Ma 2014, ʻo Jin et al.ua hoʻolālā ʻia kahi puʻupuʻu kiʻi kiʻi superlattice i hoʻohui ʻia e pili ana i ka reconfigurableLNʻO ke ala alakaʻi nalu (e like me ka hōʻike ʻana ma ke kiʻi), e loaʻa ana i ka hana kūpono o nā kiʻi entangled a me ka wikiwiki electro-optic modulation ma ka chip no ka manawa mua.I ka makahiki 2018, ua hoʻomākaukau ʻo Wei et al a me Xu et al i nā ʻōnaehana domain periodic 3D e pili ana iLNnā kristal, a ʻike i ka hana ʻana i ka beam nonlinear maikaʻi me ka hoʻohana ʻana i nā hanana domain periodic 3D ma 2019.

Hoʻohui ʻia i ka puʻupuʻu photonic ikaika ma LN (hema) a me kāna kiʻi kiʻi ('ākau)

ʻO ka hoʻomohala ʻana o ka dielectric superlattice theory ua paipai i ka noi oLNkristal a me nā kristal ferroelectric ʻē aʻe i kahi kiʻekiʻe hou, a haawi ia lakouʻO nā manaʻo noi nui i nā lasers solid-state, optical frequency comb, laser pulse compression, beam shaping and entangled light source in quantum communication.
