Iyini imoduli ye-Optical?

I-Optical modulezivame ukusetshenziselwa ukuphatha izakhiwo zemishayo yokukhanya, njengemishayo ye-laser. Idivayisi ingashintsha izici ze-beam, njengamandla okubona noma isigaba. I-modulator ngokwemvelo ye-modulated beam ibizwa ngokuthiintensity modulator, i-modulator yesigaba, imoduli ye-polarization, i-spatial Optical modulator, njll. Izinhlobo ezahlukene zamamodulators zingasetshenziswa ezinhlelweni ezihlukene, ezifana nokuxhumana kwe-fiber optic, amadivayisi wokubonisa, ama-lases ashintshiwe nge-Q noma akhiywe imodi, kanye nokulinganisa kokubona.

Uhlobo lwemodyuli ye-Optical

Kunezinhlobo eziningi ezahlukene zama-modulators:

1. Imoduli ye-Acousto-optic iyimoduli esuselwe kumphumela we-acousto-optic. Zisetshenziselwa ukushintsha noma ukulungisa ngokuqhubekayo i-amplitude ye-laser beam, ukushintsha imvamisa yokukhanya, noma ukushintsha isiqondiso sesikhala.

2. Ii-electro-optic moduleisebenzisa umphumela we-electro-optic ku-bubble Kerrs box. Angakwazi ukulinganisa isimo se-polarization, isigaba, noma amandla e-beam, noma asetshenziselwe ukukhipha ukushaya kwenhliziyo njengoba kushiwo esigabeni se-ultrashort pulse amplifiers.

3. Imoduli yokumunca ugesi iyimoduli yokuqina esetshenziswa kusidlulisi sedatha ekuxhumaneni kwe-fiber optical.

(4) Amamojula okuphazamisa, njengamamoduli e-Mach-Zehnder, ngokuvamile asetshenziswa kumasekhethi ahlanganisiwe ezithombe ukuze kudluliswe idatha yokubona.

5. I-Fiber optic modulators ingasekelwe ezimisweni ezihlukahlukene. Kungaba idivayisi ye-fiber optic yangempela, noma ingaba ingxenye yomzimba equkethe i-fiber pigtails.

6. Imoduli yekristalu ewuketshezi ilungele ukusetshenziswa kumishini yokubonisa ebonakalayo noma i-pulse shaper. Angasetshenziswa futhi njengamamojula okukhanya kwendawo, okusho ukuthi ukudlulisela kuyahlukahluka ngendawo, engasetshenziswa kumadivayisi wokubonisa.

7. I-modulation disk ingashintsha ngezikhathi ezithile amandla e-beam, asetshenziswa kwezinye izilinganiso ezithile ze-optical (njengokusebenzisa ama-amplifiers wokukhiya).

8. Amamojula we-Micromechanical (amasistimu ama-micromechanical, i-MEMS) njengama-valve okukhanya asekelwe ku-silicon kanye nezinhlaka zesibuko ezinezinhlangothi ezimbili zibaluleke kakhulu ekubonisweni kokuqagela.

9. Amamojula okukhanya ngobuningi, njengamamojula we-electro-optical, angasebenzisa indawo enkulu yomugqa futhi angasetshenziswa nasezimeni zamandla aphezulu. Ama-modulators ahlanganiswe ne-fiber, ngokuvamile ama-waveguide modulators ane-fiber pigtails, kulula ukuwahlanganisa ezinhlelweni ze-fiber optic.

Ukusetshenziswa kwe-Optical module

Ama-Optical modulators anohlu olubanzi lwezinhlelo zokusebenza emikhakheni eminingi. Okulandelayo izindawo eziyinhloko zokusetshenziswa kwama-Optical modulators kanye nezicelo zazo ezithile:

1. Ukuxhumana okubonakalayo: Ezinhlelweni zokuxhumana optical, ama-optical modulators asetshenziselwa ukulinganisa i-amplitude, imvamisa kanye nesigaba samasignali optical ukuze kudluliselwe ulwazi. Ivamise ukusetshenziswa ezinyathelweni ezibalulekile njengokuguqulwa kwe-photoelectrical, imodulation yesignali ye-optical kanye ne-demodulation. Amamojula we-Electro-optic abaluleke kakhulu ezinhlelweni zokuxhumana ze-optical ezinesivinini esikhulu, ezisetshenziswa ukuguqula amasiginali kagesi abe amasiginali okubona futhi abone ukubhala ngekhodi nokudlulisa idatha. Ngokulungisa ukuqina noma isigaba sesiginali ye-optical, imisebenzi yokushintsha ukukhanya, ukulawulwa kwezinga lokuguquguquka kanye nokuguquguquka kwesignali kungenziwa.

2. Inzwa yokubona: Imoduli yokubona ingakwazi ukubona ukukalwa nokuqapha indawo ezungezile ngokushintsha izici zesignali yokubona. Isibonelo, ngokulungisa isigaba noma i-amplitude yokukhanya, i-fiber optic gyroscopes, izinzwa ze-fiber optic pressure, njll.

3. Ukugcinwa nokucutshungulwa kwe-Optical: Ama-modulators optical asetshenziselwa ukugcinwa kwe-optical kanye nezinhlelo zokusebenza zokucubungula optical. Kwinkumbulo yokubona, amamojula abonakalayo angasetshenziswa ukubhala nokufunda ulwazi ngaphakathi nangaphandle kwemidiya yokubona. Ekucutshungulweni kwe-optical, i-modulator ye-optical ingasetshenziselwa ukwakha, ukuhlunga, ukuguquguquka kanye nokwehliswa kwezimpawu ze-optical

4. I-imaging ye-Optical: ama-modulators optical angasetshenziswa ukulinganisa isigaba kanye ne-amplitude ye-beam yokukhanya, ngaleyo ndlela kuguqule izici zesithombe emfanekisweni we-optical. Isibonelo, imodula yenkambu ekhanyayo ingasebenzisa ukumodulation kwesigaba esinezinhlangothi ezimbili ukuze kushintshwe ubude bokugxilile kanye nokujula kokugxilisa kwe-beam.

5. Ukulawula umsindo obonakalayo: Imoduli ye-optical ingalawula ukushuba kanye nemvamisa yokukhanya, ngaleyo ndlela inciphise noma icindezele umsindo obonakalayo ohlelweni lwe-optical. Ingasetshenziswa kuma-amplifiers optical, lasers kanye ne-fiber optic transmission systems ukuze kuthuthukiswe isilinganiso sesignali-to-noise kanye nokusebenza kohlelo.

6. Ezinye izinhlelo zokusebenza: ama-electro-optical modulators nawo asetshenziswa ekuhlaziyweni kwe-spectral, izinhlelo ze-radar, ukuxilongwa kwezokwelapha kanye neminye imikhakha. Ku-spectroscopy, i-electro-optical modulator ingasetshenziswa njengengxenye ye-optical spectrum analyzer yokuhlaziywa kwe-spectral kanye nesilinganiso. Kusistimu ye-radar, i-electro-optic modulator isetshenziselwa ukuguqulwa kwesignali kanye nokwehlisa. Ekuxilongweni kwezokwelapha, ama-modulators e-electro-optic asetshenziswa ekucabangeni kwe-optical and therapy.
