Modulator ea Optical ke eng?

Optical modulatorhangata li sebelisoa ho laola thepa ea maballo a leseli, joalo ka maballo a laser. Sesebelisoa se ka khona ho laola thepa ea beam, joalo ka matla a optical kapa phase. Modulator ho ea ka mofuta oa lebone le fetotsoeng le bitsoamatla modulator, modulator ea mohato, polarization modulator, spatial Optical modulator, joalo-joalo Mefuta e fapaneng ea li-modulator e ka sebelisoa lits'ebetsong tse fapaneng, tse kang likhokahano tsa fiber optic, lisebelisoa tsa ho bonts'a, lisebelisoa tsa Q-switched kapa mode-locked lasers, le tekanyo ea optical.

Mofuta oa optical module

Ho na le mefuta e 'maloa ea li-modulator:

1. Acousto-optic modulator ke modulator e thehiloeng ho phello ea acousto-optic. Li sebelisetsoa ho chencha kapa ho tsoela pele ho lokisa amplitude ea lebone la laser, ho fetola maqhubu a khanya, kapa ho fetola tsela ea sebaka.

2. Themochine oa motlakase oa motlakasee sebelisa phello ea electro-optic lebokoseng la Kerrs la bubble. Li ka fetola boemo ba polarization, mohato, kapa matla a marang-rang, kapa tsa sebelisoa bakeng sa ho ntša pulse joalo ka ha ho boletsoe karolong ea ultrashort pulse amplifiers.

3. Motlakase oa absorption modulator ke matla a matla a sebelisoang ho transmitter ea data puisanong ea optical fiber.

(4) Li-modulator tsa tšitiso, joalo ka li-modulator tsa Mach-Zehnder, hangata li sebelisoa lipotolohong tse kopaneng tsa photonic bakeng sa phetiso ea data ea optical.

5. Fiber optic modulators e ka thehoa holim'a melao-motheo e fapaneng. E ka ba sesebelisoa sa 'nete sa fiber optic, kapa e ka ba karolo ea' mele e nang le fiber pigtails.

6. Liquid crystal modulator e loketse bakeng sa kopo ho lisebelisoa tsa optical display kapa pulse shaper. Li ka sebelisoa hape e le li-modulator tsa khanya ea sebaka, ho bolelang hore phetisetso e fapana ho ea ka sebaka, se ka sebelisoang lisebelisoa tsa ponts'o.

7. Diski ea modulation e ka fetola nako le nako matla a sefate, a sebelisoang litekanyong tse itseng tse khethehileng tsa optical (tse kang ho sebelisa li-amplifiers tsa lock-in).

8. Li-modulator tsa micromechanical (micromechanical systems, MEMS) tse kang li-valve tsa leseli tse thehiloeng ka silicon le li-array tsa seipone tse peli li bohlokoa ka ho khetheha lipontšong tsa projeke.

9. Li-modulator tse ngata tsa optical, tse kang li-electro-optical modulators, li ka sebelisa sebaka se seholo sa mahlaseli 'me li ka boela tsa sebelisoa maemong a matla a phahameng. Li-modulator tse kopantsoeng ke fiber, hangata li-waveguide modulator tse nang le fiber pigtails, li bonolo ho li kopanya ho litsamaiso tsa fiber optic.

Tšebeliso ea mochine oa Optical

Li-modulator tsa Optical li na le mefuta e mengata ea lits'ebetso likarolong tse ngata. Tse latelang ke libaka tsa mantlha tsa ts'ebeliso ea li-modulators tsa Optical le lits'ebetso tsa tsona tse ikhethileng:

1. Puisano ea optical: Litsamaisong tsa puisano tsa optical, li-modulator tsa optical li sebelisetsoa ho fetola amplitude, frequency le phase of optical signals e le ho fetisetsa tlhahisoleseding. E atisa ho sebelisoa mehatong ea bohlokoa e kang photoelectrical conversion, optical signal modulation le demodulation. Li-modulator tsa elektro-optic li bohlokoa ka ho khetheha lits'ebetsong tsa puisano tsa optical tsa lebelo le holimo, tse sebelisoang ho fetolela matšoao a elektroniki hore e be mats'oao a optical le ho hlokomela khouto ea data le phetiso. Ka ho fetola matla kapa mohato oa lets'oao la optical, mesebetsi ea ho fetoha ha leseli, taolo ea sekhahla sa ho feto-fetoha le ho feto-fetoha ha lets'oao e ka phethahala.

2. Optical sensing: Optical modulator e ka lemoha tekanyo le tlhokomelo ea tikoloho ka ho fetola litšobotsi tsa lets'oao la optical. Ka mohlala, ka ho fetola karolo kapa boholo ba leseli, li-gyroscopes tsa fiber optic, li-sensor tsa khatello ea fiber optic, joalo-joalo.

3. Ho boloka le ho sebetsana le optical: Li-modulator tsa optical li sebelisoa bakeng sa polokelo ea optical le li-optical processing applications. Ka mohopolong oa optical, li-modulator tsa optical li ka sebelisoa ho ngola le ho bala tlhahisoleseling ho tsoa le ho tsoa mecheng ea litaba. Ts'ebetsong ea optical, modulator ea optical e ka sebelisoa bakeng sa ho theha, ho sefa, ho feto-fetoha le ho fokotsa matšoao a optical.

4. Litšoantšo tsa optical: li-modulator tsa optical li ka sebelisoa ho fetola mohato le amplitude ea khanya ea leseli, ka hona ho fetola litšobotsi tsa setšoantšo ka litšoantšo tsa optical. Mohlala, modulator ea lebala e bobebe e ka kenya tšebetsong modulation ea mekhahlelo e 'meli ho fetola bolelele ba tsepamiso le botebo bo tsepamisitsoeng ba leballo.

5. Taolo ea lerata ea optical: Mochine oa optical o ka laola matla le makhetlo a mangata a khanya, kahoo a fokotsa kapa a hatella lerata la optical tsamaisong ea optical. E ka sebelisoa ho li-amplifiers tsa optical, lasers le fiber optic transmission systems ho ntlafatsa karo-karolelano ea lerata le ts'ebetso ea tsamaiso.

6. Lisebelisoa tse ling: li-electro-optical modulators li boetse li sebelisoa ho hlahloba spectral, mekhoa ea radar, tlhahlobo ea bongaka le masimo a mang. Ho spectroscopy, electro-optical modulator e ka sebelisoa e le karolo ea optical spectrum analyzer bakeng sa tlhahlobo ea spectral le tekanyo. Sistimi ea radar, electro-optic modulator e sebelisoa bakeng sa ho feto-fetoha ha lets'oao le ho nyenyefatsa. Ha ho hlahlojoa bongaka, li-electro-optic modulators li sebelisoa ho imaging le kalafong ea optical.
