Tšebeliso ea theknoloji eamodulator ea electro-optic
Sesebelisoa sa Electro-optic (modulator ea Electro-optic)Modulator ea EOM） ke karolo ea taolo ea lets'oao e sebelisang phello ea electro-optic ho fetola khanya ea leseli. Molao-motheo oa eona oa ts'ebetso o atisa ho finyelloa ka phello ea Pockels (Tšusumetso ea Pockels, e leng phello ea Pockels), e sebelisang monyetla oa ketsahalo ea hore index ea refractive ea thepa ea optical e seng ea linear e fetoha tlas'a ts'ebetso ea masimo a motlakase.
Sebopeho sa motheo sa modulator ea electro-optic hangata se kenyelletsa kristale (kristale ea Pockels) e nang le phello ea electro-optical, 'me thepa e tloaelehileng ke lithium niobate (LiNbO₃). Motlakase o hlokahalang ho baka phetoho ea mohato o bitsoa motlakase oa Half-wave. Bakeng sa likristale tsa Pockels, hangata ho hlokahala li-volt tse makholo kapa esita le likete, ka hona tlhoko ea li-amplifiers tsa voltage e phahameng. Potoloho e loketseng ea elektroniki e ka fetola motlakase o phahameng joalo ka metsotsoana e seng mekae, e leng se lumellang EOM ho sebelisoa e le switch e potlakileng ea optical; Ka lebaka la tlhaho ea capacitive ea likristale tsa Pockels, bakhanni bana ba hloka ho fana ka palo e kholo ea hona joale (tabeng ea switch e potlakileng kapa modulation, capacitance e lokela ho fokotsoa ho fokotsa tahlehelo ea matla). Maemong a mang, joalo ka ha ho hlokahala amplitude e nyane kapa modulation ea mohato, ho hlokahala motlakase o monyane feela bakeng sa modulation. Lisebelisoa tse ling tsa kristale tse seng mola tse sebelisoang ho li-modulator tsa electro-optical (Modulator ea EOM) li kenyelletsa potassium titanate (KTP), beta-barium borate (BBO, e loketseng matla a mahareng a phahameng le/kapa maqhubu a ho fetola a phahameng), lithium tantalate (LiTaO3), le ammonium phosphate (NH4H2PO4, ADP, e nang le thepa e itseng ea electro-optical).
Li-modulator tsa Electro-optic (modulator ea electro-optic)Modulator ea EO） li bontša bokhoni ba bohlokoa ba ts'ebeliso masimong a 'maloa a theknoloji e phahameng:
1. Puisano ea faeba ea optical: Marang-rang a sejoale-joale a puisano, li-modulator tsa electro-optical（Modulator ea EO） li sebelisetsoa ho fetola matšoao a optical, ho netefatsa phetiso ea data e sebetsang hantle le e tšepahalang libakeng tse telele. Ka ho laola hantle mohato kapa boholo ba khanya, phetiso ea tlhahisoleseling e lebelo le phahameng le e nang le bokhoni bo boholo e ka finyelloa.
2. Spectroskopia e nepahetseng: Modulator ea electro-optical e fetola mohloli oa leseli ka har'a spectrometer ho ntlafatsa ho nepahala ha tekanyo. Ka ho fetola ka potlako maqhubu kapa mohato oa lets'oao la optical, tlhahlobo le ho khetholla likarolo tse rarahaneng tsa lik'hemik'hale li ka tšehetsoa, 'me qeto le kutlo ea tekanyo ea spectral li ka ntlafatsoa.
3. Tshebetso ya data ya optical e sebetsang hantle: modulator ya electro-optical tsamaisong ya khomphutha ya optical le ya ts'ebetso ya data, ka ho fetola matshwao a optical ka nako ya sebele ho ntlafatsa lebelo la ts'ebetso ya data le ho tenyetseha. Ka tšobotsi ya karabelo e potlakileng ya EOM, ts'ebetso le phetisetso ya data ya optical ya lebelo le phahameng le latency e tlase e ka phethahala.
4. Theknoloji ea laser: Modulator ea electro-optic e ka laola mohato le boholo ba lehlaseli la laser, e fana ka tšehetso bakeng sa ho nka litšoantšo ka nepo, ts'ebetso ea laser le lits'ebetso tse ling. Ka ho fetola liparamente tsa lehlaseli la laser ka nepo, ts'ebetso ea laser ea boleng bo holimo e ka finyelloa.
