LiNbO3 modulatorUsoro modulator bụ isi ihe nwere ike ijikwa mgbanwe akụkụ nke ebili mmiri ọkụ, ọ na-arụkwa ọrụ dị mkpa na nzikọrịta ozi na nghọta nke ọgbara ọhụrụ.Na nso nso a, ụdị ọhụrụusoro modulatoradọtala uche nke ndị na-eme nchọpụta na ndị injinia, nke na-arụ ọrụ n'ogologo atọ nke 780nm, 850nm na 1064nm, na bandwit modulation ruru 300MHz, 10GHz, 20GHz na 40GHz.
Akụkụ kachasị mkpa nke modulator nke oge a bụ bandwit modulation dị elu na nkwụsị ntinye dị ala.Ọnwụ ntinye na-ezo aka na mbelata ike ma ọ bụ ike nke mgbama ngwa anya mgbe ọ gafesịrị modulator.Mfu ntinye nke modulator usoro a dị oke ala, nke na-eme ka iguzosi ike n'ezi ihe nke mgbaàmà ahụ, ka mgbaàmà ahụ wee nwee ike ịnọgide na-enwe ike dị elu mgbe mgbanwe mgbanwe gasịrị.
Na mgbakwunye, modulator na-eme ihe nwere njirimara nke obere voltaji ọkara-ebili mmiri.Voltage ọkara nke ebili mmiri bụ voltaji achọrọ ka etinyere ya na modulator iji gbanwee oge ọkụ ahụ site na ogo 180.Obere obere voltaji nke ọkara pụtara na ọ bụ naanị obere voltaji dị mkpa iji nweta mgbanwe dị ukwuu na mpaghara anya, nke na-ebelata oke ike ike nke ngwaọrụ ahụ.
N'ihe gbasara mpaghara ngwa, enwere ike iji modulator usoro ọhụrụ a mee ihe n'ọtụtụ ebe na nhụta eriri anya, nkwurịta okwu fiber anya, igbu oge oge (shifter), na nkwurịta okwu quantum.Na nhụta eriri anya, modulator usoro nwere ike imeziwanye nghọta na mkpebi nke ihe mmetụta.Na nkwurịta okwu eriri anya, ọ nwere ike imeziwanye ọsọ nzikọrịta ozi yana arụmọrụ nnyefe data.Na oge igbu oge (shifter), ọ nwere ike ịchịkwa ntụziaka nke mgbasa ọkụ;Na nzikọrịta ozi quantum, enwere ike iji ya jikwaa ma megharịa steeti quantum.
N'ozuzu, modulator usoro ọhụrụ na-enye anyị ụzọ njikwa anya nke ọma na nke ziri ezi, nke ga-eweta mgbanwe mgbanwe n'ọtụtụ mpaghara.Anyị na-atụ anya na teknụzụ a ga-emepewanye ma zuo oke n'ọdịnihu, na-ekpughere anyị ihe omimi ndị ọzọ.
