Xyoo 1962, Armstrong et al.thawj lub tswv yim ntawm QPM (Quasi-phase-match), uas siv cov inverted lattice vector muab los ntawm superlattice los them nyiajphase mismatch nyob rau hauv optical parametric txheej txheem.Kev taw qhia polarization ntawm ferroelectricscawvs tus nonlinear polarization tus nqi χ². QPM tuaj yeem pom tau los ntawm kev npaj cov qauv ferroelectric domain nrog cov lus qhia ntawm lub sijhawm polarization nyob rau hauv lub cev ferroelectric, suav nrog lithium niobate, lithium tantalate, thiabKTPsiv lead ua.LN siv lead uadav tshaj plawssivkhoomhauv daim teb no.

Xyoo 1969, Camlibel tau tshaj tawm tias ferroelectric domain ntawmLNthiab lwm yam ferroelectric muaju tuaj yeem thim rov qab los ntawm kev siv hluav taws xob hluav taws xob siab tshaj 30 kV / mm.Txawm li cas los xij, xws li hluav taws xob siab tuaj yeem puncture cov siv lead ua tau yooj yim.Nyob rau lub sijhawm ntawd, nws nyuaj rau kev npaj cov txheej txheem electrode zoo thiab raug tswj xyuas cov txheej txheem kev thim rov qab sau npe.Txij thaum ntawd los, kev sim tau ua los tsim cov txheej txheem ntau lub npe los ntawm kev hloov lamination ntawmLNmuaju nyob rau hauv cov lus qhia sib txawv polarization, tab sis tus naj npawb ntawm cov chips uas tuaj yeem paub tau yog txwv.Xyoo 1980, Feng et al.tau siv lead ua nrog lub sij hawm polarization domain qauv los ntawm txoj kev ntawm eccentric kev loj hlob los ntawm biasing lub siv lead ua rotation center thiab thermal teb axisy-symmetric center, thiab pom tau hais tias lub zaus ob npaug rau tso zis ntawm 1.06 μm laser, uas txheeb xyuas qhovQPMkev xav.Tab sis txoj kev no muaj teeb meem loj hauv kev tswj kom zoo ntawm cov qauv raws sij hawm.Xyoo 1993, Yamada et al.ua tiav kev daws teeb meem ntawm cov txheej txheem polarization inversion raws sij hawm los ntawm kev sib txuas cov txheej txheem semiconductor lithography nrog rau txoj kev siv hluav taws xob teb.Siv hluav taws xob teb polarization txoj kev tau maj mam dhau los ua cov txheej txheem kev npaj cov txheej txheem ntawm lub caij nyoog poledLNsiv lead ua.Tam sim no, lub periodic poledLNCrystal tau ua lag luam thiab nws cov thickness tuaj yeem ua taubentau tshaj 5 mm.

Thawj daim ntawv thov ntawm periodic poledLNCrystal feem ntau yog txiav txim siab rau laser zaus hloov dua siab tshiab.Thaum ntxov li 1989, Ming et al.npaj lub tswvyim ntawm dielectric superlattices raws li cov superlattices tsim los ntawm ferroelectric domains ntawmLNsiv lead ua.Lub inverted lattice ntawm superlattice yuav koom nrog hauv kev ua kom zoo siab thiab nthuav tawm ntawm lub teeb thiab lub suab nthwv dej.Xyoo 1990, Feng thiab Zhu et al.tau npaj txoj kev xav ntawm ntau quasi matching.Xyoo 1995, Zhu et al.npaj quasi-periodic dielectric superlattices los ntawm chav sov polarization txheej txheem.Hauv xyoo 1997, kev sim tshuaj xyuas tau ua tiav, thiab kev sib txuas ua haujlwm tau zoo ntawm ob qhov txheej txheem kho qhov muag-zaus ob npaug thiab zaus summing tau pom nyob rau hauv ib tug quasi-periodic superlattice, yog li ua tau zoo laser triple zaus ob npaug rau thawj zaug.Xyoo 2001, Liu et al.tsim ib lub tswv yim kom paub peb-xim laser raws li quasi-theem txuam.Nyob rau hauv 2004, Zhu et al pom tau hais tias lub optical superlattice tsim ntawm multi-wavelength laser tso zis thiab nws daim ntawv thov nyob rau hauv tag nrho cov-solid-state lasers.Nyob rau hauv 2014, Jin et al.tsim ib qho optical superlattice integrated photonic nti raws li reconfigurableLNwaveguide kho qhov muag txoj kev (raws li qhia nyob rau hauv daim duab), ua tau zoo tiam ntawm entangled photons thiab high-speed electro-optic modulation ntawm lub nti thawj zaug.Xyoo 2018, Wei et al thiab Xu et al tau npaj 3D lub sijhawm sau npe raws liLNcrystals, thiab pom tau hais tias muaj txiaj ntsig zoo ntawm cov kab hluav taws xob tsis zoo siv 3D lub sijhawm sau cov qauv hauv xyoo 2019.

Integrated active photonic nti ntawm LN (sab laug) thiab nws daim duab schematic (txoj cai)

Txoj kev loj hlob ntawm dielectric superlattice txoj kev xav tau txhawb nqa daim ntawv thov ntawmLNsiv lead ua thiab lwm yam ferroelectric crystals mus rau qhov siab tshiab, thiab muab rau lawvQhov tseem ceeb daim ntawv thov kev cia siab nyob rau hauv tag nrho cov-solid-state lasers, kho qhov muag zaus zuag, laser mem tes compression, beam shaping thiab entangled teeb qhov chaw nyob rau hauv quantum kev sib txuas lus.
