I-Eo Modulator Series: Kutheni i-lithium niobate ibizwa ngokuba yi-silicon ebonakalayo

I-Lithium niobate ikwabizwa ngokuba yi-silicon ebonakalayo. Kukho intetho ethi "i-lithium niobate kukunxibelelana okubonakalayo ukuba yintoni i-silicon kwii-semiconductors." Ukubaluleka kwe-silicon kwi-electronics revolution, ngoko ke yintoni eyenza ishishini libe nethemba malunga nezixhobo ze-lithium niobate?

I-Lithium niobate (i-LiNbO3) yaziwa ngokuba yi "silicon optical" kwishishini. Ukongeza kwizinto eziluncedo zendalo ezifana nozinzo olulungileyo lomzimba kunye neekhemikhali, ifestile evulekileyo ebanzi (0.4m ~ 5m), kunye ne-coefficient enkulu ye-electro-optical (33 = 27 pm/V), i-lithium niobate ikwaluhlobo lwekristale ekrwada eninzi. imithombo yezinto eziphathekayo kunye nexabiso eliphantsi. Isetyenziswa ngokubanzi kwiifilitha eziphezulu zokusebenza, izixhobo ze-electro-optical, i-holographic storage, i-3D holographic display, izixhobo ze-optical nonlinear, i-optical quantum communication kunye nokunye. Kwintsimi yonxibelelwano lwe-optical, i-lithium niobate idlala indima enkulu yokuguqulwa kokukhanya, kwaye ibe yimveliso eqhelekileyo kwimodyuli yangoku ye-electro-optical modulator (Eo Modulator) imarike.

Okwangoku, kukho iitekhnoloji ezintathu eziphambili zokumodareyitha ukukhanya kwishishini: iimodyuli ze-electro-optical (Eo Modulator) esekwe kukukhanya kwesilicon, i-indium phosphide kunyelithium niobateamaqonga eziphathekayo. Imodyuli ye-silicon optical isetyenziswa ikakhulu kwiimodyuli zonxibelelwano lwedatha olufutshane, imodyuli ye-indium phosphide isetyenziswa ikakhulu kuluhlu oluphakathi kunye nolude lweemodyuli zonxibelelwano lwe-optical network transceiver, kunye ne-lithium niobate electro-optical modulator (Eo Modulator) isetyenziswa kakhulu umqolo omde womnatha wonxibelelwano oluhambelanayo kunye ne-single-wave 100/200Gbps amaziko edatha ye-ultra-high-speed. Phakathi kwezi qonga zintathu zingentla zesantya esiphezulu semodyuli, ifilim ebhityileyo i-lithium niobate modulator eye yavela kwiminyaka yakutshanje ine-advanteji ye-bandwidth ukuba ezinye izinto azikwazi ukuhambelana.

I-Lithium niobate luhlobo lwe-inorganic substance, i-chemical formulaLiNbO3, i-crystal engathandekiyo, i-crystal ye-ferroelectric, i-polarized lithium niobate crystal ene-piezoelectric, i-ferroelectric, i-photoelectric, i-nonlinear optics, i-thermoelectric kunye nezinye iipropati zezinto eziphathekayo, ngexesha elifanayo ne-photorefractive effect. I-Lithium niobate crystal yenye yezona zinto zisetyenziswa kakhulu kwi-inorganic materials, yinto efanelekileyo yokutshintshiselana kwamandla e-piezoelectric, izinto ze-ferroelectric, izinto ze-electro-optical, i-lithium niobate njengesixhobo se-electro-optical kunxibelelwano lwe-optical ludlala indima ekumodareyitheni ukukhanya.

Izinto ze-lithium niobate, ezaziwa ngokuba yi-"silicon optical", isebenzisa inkqubo yamva nje ye-micro-nano ukuphunga i-silicon dioxide (SiO2) umaleko kwi-silicon substrate, ibophe i-lithium niobate substrate kubushushu obuphezulu ukwakha umphezulu wokucanda, kwaye ekugqibeleni ixobulise. ngaphandle kwefilimu ye-lithium niobate. Ifilimu elungiselelwe i-lithium niobate modulator ineenzuzo zokusebenza okuphezulu, ixabiso eliphantsi, ubungakanani obuncinci, ukuveliswa kobuninzi, kunye nokuhambelana nobuchwepheshe be-CMOS, kwaye isisombululo sokukhuphisana kwi-high-speed optical interconnection kwixesha elizayo.

Ukuba iziko le-electronic revolution libizwa ngegama le-silicon eyenze ukuba kwenzeke, ke i-photonics revolution inokulandelwa kwizinto eziphathekayo ze-lithium niobate, ezaziwa ngokuba yi "silicon optical" i-lithium niobate yinto engenambala ecacileyo edibanisa iziphumo ze-photorefractive, nonlinear. iziphumo, i-electro-optical effects, i-acousto-optical effects, i-piezoelectric effects kunye ne-thermal effects. Uninzi lweepropathi zalo lunokulawulwa ngokubunjwa kwekristale, i-doping element, ulawulo lwe-valence kunye nezinye izinto. Isetyenziswa ngokubanzi ukulungiselela i-waveguide optical, switch optical, imodyuli yepiezoelectric,imodyuli ye-electro-optical, ijeneretha yesibini ye-harmonic, i-laser frequency multiplier kunye nezinye iimveliso. Kwishishini lonxibelelwano lwamehlo, iimodyuli ziyintengiso ebalulekileyo yesicelo se-lithium niobate.
