Ngo-1962, u-Armstrong et al.okokuqala iphakamise umqondo we-QPM (i-Quasi-phase-match), esebenzisa i-vector ye-lattice ehlanekezelwe ehlinzekwa yi-superlattice ukuze kunxeshezelwepUkungafani kahle kwe-optical parametric process.Isiqondiso se-polarization yama-ferroelectricsithonyas izinga le-polarization elingaqondile χ². I-QPM ingenzeka ngokulungiselela izakhiwo zesizinda se-ferroelectric ezinezikhombisi-ndlela ezihlukile ze-polarization emizimbeni ye-ferroelectric, kuhlanganise ne-lithium niobate, lithium tantalate, futhiI-KTPamakristalu.I-LN crystal yiyonakabanzi kakhuluesetshenzisiweimpahlakulo mkhakha.

Ngo-1969, uCamlibel wenza isiphakamiso sokuthi isizinda sikagesi se-ferroelectricLNnamanye amakristalu e-ferroelectric angahlehliswa ngokusebenzisa inkambu kagesi yamandla aphezulu ngaphezu kuka-30 kV/mm.Nokho, inkambu kagesi ephakeme kangako ingabhoboza kalula ikristalu.Ngaleso sikhathi, kwakunzima ukulungiselela izakhiwo ezinhle ze-electrode nokulawula ngokunembile inqubo yokuguqula isizinda se-polarization.Kusukela lapho, kuye kwenziwa imizamo yokwakha isakhiwo sesizinda esiningi ngokushintshanisa i-lamination yeLNamakristalu ezindaweni ezahlukene ze-polarization, kodwa inani lama-chips angabonakala lilinganiselwe.Ngo-1980, uFeng et al.ithole amakristalu anesakhiwo sesizinda se-periodic polarization ngendlela yokukhula kwe-eccentric ngokuchema isikhungo se-crystal rotation kanye nesikhungo esishisayo se-axisy-symmetric centre, futhi yabona ukuphuma okuphindwe kabili kwe-1.06 μm laser, okuqinisekiseQPMumbono.Kodwa le ndlela inobunzima obukhulu ekulawuleni okuhle kwesakhiwo sezikhathi ezithile.Ngo-1993, u-Yamada et al.ixazulule ngempumelelo inqubo yokuguqula isizinda se-polarization ngokuhlanganisa inqubo ye-semiconductor lithography kanye nendlela yensimu kagesi esetshenziswayo.Indlela ye-polarization yensimu kagesi esetshenziswayo isiphenduke ubuchwepheshe bokulungiselela obujwayelekile be-periodic poleLNikristalu.Njengamanje, i-periodic isiphelileLNIkristalu yenziwe ukuhweba futhi ukushuba kwayo kungababengaphezu kuka-5 mm.

Ukusetshenziswa kokuqala kwe-periodic poleLNI-crystal ibhekwa ngokuyinhloko ekuguquleni imvamisa ye-laser.Kusukela ngo-1989, uMing et al.ihlongoze umqondo we-dielectric superlattices esekelwe kuma-superlattice akhiwe kusuka ezizindeni ze-ferroelectricLNamakristalu.I-lattice ehlanekezelwe ye-superlattice izobamba iqhaza ekusaseni nasekusakazeni amaza okukhanya nawomsindo.Ngo-1990, uFeng noZhu et al.ihlongoze ithiyori yokumataniswa kwe-quasi okuningi.Ngo-1995, uZhu et al.kulungiswe i-quasi-periodic dielectric superlattices ngenqubo ye-polarization yegumbi.Ngo-1997, ukuqinisekiswa kokuhlolwa kwenziwa, futhi kwahlanganiswa ngempumelelo izinqubo ezimbili ze-optical parametric.-ukuphindwa kabili kwefrequency kanye nokufingqa kwefrikhwensi kwatholwa nge-quasi-periodic superlattice, ngaleyo ndlela kuzuzwe ukusebenza kahle kwe-laser triple frequency kabili ngokokuqala ngqa.Ngo-2001, uLiu et al.uklame uhlelo lokubona i-laser enemibala emithathu esuselwe ekufanisweni kwesigaba se-quasi.Ngo-2004, u-Zhu et al wabona idizayini ye-optical superlattice yokuphuma kwe-laser enamaza amaningi kanye nokusetshenziswa kwayo kumalaser aso sonke isimo esiqinile.Ngo-2014, uJin et al.idizayine i-optical superlattice ehlanganisiwe ye-photonic chip esekelwe ekulungisekeni kabushaLNi-waveguide optical path (njengoba kukhonjisiwe emfanekisweni), ithola ukukhiqizwa okuphumelelayo kwamafotoni abambenekezelwe kanye nokuguqulwa kwe-electro-optic okunesivinini esiphezulu ku-chip okokuqala ngqa.Ngo-2018, u-Wei et al no-Xu et al balungiselela izakhiwo zesizinda se-3D ezisekelweLNamakristalu, futhi yabona ukubunjwa okusebenzayo kwe-nonlinear kusetshenziswa izakhiwo zesizinda se-3D ngezikhathi ezithile ngo-2019.

I-chip yesithombe esebenzayo ehlanganisiwe ku-LN (kwesokunxele) kanye nomdwebo wayo wohlelo(kwesokudla)

Ukuthuthukiswa kwethiyori ye-dielectric superlattice kukhuthaze ukusetshenziswa kweLNikristalu namanye amakristalu e-ferroelectric afinyelele ukuphakama okusha, wabanikaamathemba okusebenza abalulekile kuma-laser-solid-state, ikamu le-optical frequency, i-laser pulse compression, ukubunjwa kwe-beam kanye nemithombo yokukhanya ebambene ekuxhumaneni kwe-quantum.
