Modulator ea elektro-optic.EOM modulator） ke karolo ea taolo ea lets'oao e sebelisang phello ea elektro-optic ho hlophisa lebone le khanyang. Molao-motheo oa eona oa ho sebetsa o finyelloa ka kakaretso ka phello ea Pockels (Pockels effect, e leng Pockels effect), e nka monyetla ka ketsahalo ea hore index ea refractive ea lintho tse sa tloaelehang tsa optical e fetoha tlas'a ketso ea masimo a motlakase.
Sebopeho sa motheo sa electro-optic modulator hangata se kenyelletsa kristale (Pockels crystal) e nang le phello ea electro-optical, 'me thepa e tloaelehileng ke lithium niobate (LiNbO₃). Matla a motlakase a hlokahalang bakeng sa phetoho ea mohato o bitsoa Half-wave voltage. Bakeng sa likristale tsa Pockels, hangata ho hlokahala li-volts tse makholo kapa tse likete, ka hona tlhokahalo ea li-amplifiers tse phahameng. Potoloho e nepahetseng ea elektronike e ka fetola matla a phahameng joalo ka li-nanoseconds tse 'maloa, e leng ho lumellang EOM hore e sebelisoe e le mochine o potlakileng oa 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 ho fetola ka potlako kapa ho feto-fetoha ha molumo, bokhoni bo lokela ho fokotsoa ho fokotsa tahlehelo ea matla). Maemong a mang, joalo ka ha ho hlokahala feela amplitude e nyane kapa modulation ea phase, ho hlokahala feela motlakase o monyane bakeng sa ho feto-fetoha ha molumo. Lisebelisoa tse ling tsa kristale tse se nang moeli tse sebelisoang ho li-modulator tsa electro-optical (EOM modulator) kenyeletsa potassium titanate (KTP), beta-barium borate (BBO, e loketseng matla a karolelano e phahameng le / kapa maqhubu a phahameng a ho fetola), lithium tantalate (LiTaO3), le ammonium phosphate (NH4H2PO4, ADP, e nang le lisebelisoa tse khethehileng tsa electro-optical).
Li-modulators tsa elektro-optic.EO modulator） bonts'a bokhoni ba ts'ebeliso ea bohlokoa mafapheng a 'maloa a theknoloji e phahameng:
1. Puisano ea fiber ea mahlo: Marang-rang a sejoale-joale a likhokahano tsa mehala, li-modulator tsa electro-optical.EO modulator） li sebelisetsoa ho fetola mats'oao a mahlo, ho netefatsa phetisetso ea data e sebetsang hantle le e tšepahalang libakeng tse telele. Ka ho laola ka nepo mohato kapa boholo ba leseli, phetiso ea tlhahisoleseling e potlakileng le e matla e ka finyelloa.
2. Precision spectroscopy: Modulator ea electro-optical e fetola mohloli oa leseli ho spectrometer ho ntlafatsa ho nepahala ha tekanyo. Ka ho fetola ka potlako lebelo kapa mohato oa pontšo ea optical, tlhahlobo le ho khetholla likarolo tse rarahaneng tsa lik'hemik'hale li ka tšehetsoa, 'me qeto le kutloisiso ea tekanyo ea spectral li ka ntlafatsoa.
3. Ts'ebetso e phahameng ea ts'ebetso ea optical data: electro-optical modulator ho optical computing le data processing system, ka nako ea sebele ea ho feto-fetoha ha matšoao a optical ho ntlafatsa lebelo la ts'ebetso ea data le ho feto-fetoha ha maemo. Ka tšobotsi ea karabo e potlakileng ea EOM, ts'ebetso ea data ea optical e potlakileng le e tlase ea latency le phetisetso e ka phethahala.
4. Theknoloji ea laser: Motlakase oa electro-optic o ka laola mohato le amplitude ea lebone la laser, ho fana ka ts'ehetso bakeng sa litšoantšo tse nepahetseng, ts'ebetso ea laser le lisebelisoa tse ling. Ka ho hlophisa ka nepo li-parameter tsa beam ea laser, ts'ebetso ea boleng bo holimo ea laser e ka fihlelleha.
