Modulator ea Optical ke eng?
Modulator ea Opticalhangata li sebelisoa ho laola litšobotsi tsa mabone a khanya, joalo ka mabone a laser. Sesebelisoa se ka laola litšobotsi tsa mabone, joalo ka matla a optical kapa phase. Modulator ho latela mofuta oa mabone a fetotsoeng e bitsoamodulator ea matla, modulator ea mohato, modulator ea polarization, modulator ea Optical ea sebaka, jj. Mefuta e fapaneng ea li-modulator e ka sebelisoa lits'ebetsong tse fapaneng, joalo ka puisano ea fiber optic, lisebelisoa tsa ponts'o, lasers ea Q-switched kapa mode-locked, le tekanyo ea optical.
Mofuta oa modulator ea optical
Ho na le mefuta e fapaneng ea li-modulator:
1. Modulator ea Acousto-optic ke modulator e thehiloeng ho phello ea acousto-optic. Li sebelisetsoa ho fetola kapa ho fetola bophahamo ba lehlaseli la laser khafetsa, ho fetola maqhubu a khanya, kapa ho fetola tataiso ea sebaka.
2. Themodulator ea electro-optice sebelisa phello ea electro-optic ka lebokoseng la bubble Kerrs. Li ka fetola boemo ba polarization, phase, kapa matla a mahlaseli, kapa tsa sebelisoa bakeng sa ho ntša pulse joalo ka ha ho boletsoe karolong e buang ka li-amplifiers tsa pulse tse khutšoane haholo.
3. Modulator ea ho monya motlakase ke modulator ea matla e sebelisoang ho transmitter ea data puisanong ea fiber ea optical.
(4) Li-modulator tsa tšitiso, tse kang li-modulator tsa Mach-Zehnder, hangata li sebelisoa lipotolohong tse kopantsoeng tsa photonic bakeng sa phetiso ea data ea optical.
5. Li-modulator tsa fiber optic li ka ipapisa le melao-motheo e fapaneng. E ka ba sesebelisoa sa 'nete sa fiber optic, kapa e ka ba karolo ea 'mele e nang le li-pigtail tsa fiber.
6. Modulator ea kristale ea metsi e loketse ho sebelisoa lisebelisoa tsa ponts'o ea optical kapa pulse shaper. Li ka boela tsa sebelisoa e le li-modulator tsa leseli la sebaka, ho bolelang hore phetiso e fapana ho latela sebaka, e ka sebelisoang lisebelisoa tsa ponts'o.
7. Diski ya modulation e ka fetola matla a lehlasedi nako le nako, e sebediswang ditekanyong tse itseng tsa optical (jwalo ka ho sebedisa di-amplifiers tsa ho notlela).
8. Li-modulator tsa micromechanical (litsamaiso tsa micromechanical, MEMS) tse kang li-valve tsa leseli tse thehiloeng ho silicon le li-array tsa seipone tse nang le mahlakore a mabeli li bohlokoa haholo lipontšong tsa projeke.
9. Li-modulator tsa optical tse ngata, tse kang li-modulator tsa electro-optical, li ka sebelisa sebaka se seholo sa mahlaseli 'me li ka boela tsa sebelisoa maemong a matla a phahameng. Li-modulator tse kopantsoeng le faeba, hangata li-modulator tsa waveguide tse nang le li-pigtail tsa faeba, li bonolo ho li kopanya le litsamaiso tsa fiber optic.
Tšebeliso ea modulator ea Optical
Li-modulator tsa Optical li na le mefuta e mengata ea lits'ebetso masimong a mangata. Tse latelang ke libaka tsa mantlha tsa ts'ebeliso ea li-modulator tsa Optical le lits'ebetso tsa tsona tse ikhethileng:
1. Puisano ea Optical: Litsamaisong tsa puisano ea optical, li-modulator tsa optical li sebelisoa ho fetola boholo, maqhubu le mohato oa matšoao a optical e le ho fetisa tlhahisoleseling. Hangata e sebelisoa mehatong ea bohlokoa joalo ka phetoho ea photoelectrical, modulation ea lets'oao la optical le demodulation . Li-modulator tsa electro-optic li bohlokoa haholo litsamaisong tsa puisano ea optical tse potlakileng, tse sebelisetsoang ho fetola matšoao a elektroniki hore e be matšoao a optical le ho etsa hore data e ngoloe le ho fetisoa. Ka ho fetola matla kapa mohato oa lets'oao la optical, mesebetsi ea ho fetola leseli, taolo ea sekhahla sa modulation le modulation ea lets'oao e ka phethahala
2. Ho lemoha mahlo: Modulator ea mahlo e ka hlokomela tekanyo le tlhokomelo ea tikoloho ka ho fetola litšobotsi tsa lets'oao la mahlo. Mohlala, ka ho fetola mohato kapa boholo ba khanya, li-gyroscope tsa fiber optic, li-sensor tsa khatello ea fiber optic, jj. li ka bonoa
3. Polokelo le ts'ebetso ea mahlo: Li-modulator tsa mahlo li sebelisoa bakeng sa ts'ebeliso ea polokelo ea mahlo le ts'ebetso ea mahlo. Ho memori ea mahlo, li-modulator tsa mahlo li ka sebelisoa ho ngola le ho bala tlhahisoleseling kahare le kantle ho mecha ea phatlalatso ea mahlo. Ts'ebetsong ea mahlo, modulator ea mahlo e ka sebelisoa bakeng sa ho theha, ho sefa, ho fetola le ho tlosa matšoao a mahlo
4. Ho nka ditshwantsho tsa mahlo: di-modulator tsa mahlo di ka sebediswa ho fetola mohato le boholo ba lehlasedi la lesedi, ka hona di fetola dibopeho tsa setshwantsho ho nka ditshwantsho tsa mahlo. Mohlala, modulator ya tshimo ya lesedi e ka kenya tshebetsong modulation ya mohato wa mahlakore a mabedi ho fetola bolelele ba focal le botebo ba ho tsepamisa maikutlo ba lehlasedi
5. Taolo ea lerata la mahlo: Modulator ea mahlo e ka laola matla le maqhubu a khanya, ka hona ea fokotsa kapa ea hatella lerata la mahlo tsamaisong ea mahlo. E ka sebelisoa ho li-amplifier tsa mahlo, li-laser le litsamaiso tsa phetisetso ea fiber optic ho ntlafatsa karolelano ea lets'oao-lerata le ts'ebetso ea sistimi
6. Ditshebediso tse ding: di-modulator tsa electro-optical le tsona di sebediswa tlhahlobong ya spectral, ditsamaisong tsa radar, tlhahlobong ya bongaka le mafapheng a mang. Ho spectroscopy, modulator ya electro-optical e ka sebediswa e le karolo ya mohlahlobi wa spectrum ya optical bakeng sa tlhahlobo le tekanyo ya spectral. Tsamaisong ya radar, modulator ya electro-optic e sebediswa bakeng sa ho fetola matshwao le ho atoloha ha matshwao. Tlhahlobong ya bongaka, di-modulator tsa electro-optic di sebediswa ho setshwantsho sa optical le kalafong .
