Iyini i-Optical modulator?
I-modulator yokukhanyazivame ukusetshenziselwa ukushintsha izakhiwo zemisebe yokukhanya, njengemisebe ye-laser. Idivayisi ingaguqula izakhiwo zemisebe, njengamandla okukhanya noma isigaba. I-Modulator ngokwesimo semisebe eguquliwe ibizwa ngokuthii-modulator yokuqina, i-modulator yesigaba, i-polarization modulator, i-spatial Optical modulator, njll. Izinhlobo ezahlukene zama-modulator zingasetshenziswa ezinhlelweni zokusebenza ezahlukene, njengokuxhumana kwe-fiber optic, amadivayisi okubonisa, ama-laser e-Q-switched noma i-mode-locked, kanye nokulinganisa kwe-optical.
Uhlobo lwe-modulator ye-optical
Kunezinhlobo eziningana ezahlukene zama-modulator:
1. I-Acousto-optic modulator iyi-modulator esekelwe kumphumela we-acousto-optic. Isetshenziselwa ukushintsha noma ukulungisa njalo ubukhulu bomsebe we-laser, ukushintsha imvamisa yokukhanya, noma ukushintsha isiqondiso sesikhala.
2. Ii-electro-optic modulatorisebenzisa umphumela we-electro-optic ebhokisini le-bubble Kerrs. Zingaguqula isimo se-polarization, isigaba, noma amandla e-beam, noma zisetshenziselwe ukukhipha i-pulse njengoba kushiwo esigabeni sama-amplifiers e-pulse amafushane kakhulu.
3. I-modulator yokumunca kagesi iyi-modulator yokuqina esetshenziswa kusithumeli sedatha ekuxhumaneni nge-optical fiber.
(4) Ama-modulators okuphazamisa, njenge-Mach-Zehnder modulators, avame ukusetshenziswa kumasekethe ahlanganisiwe e-photonic ukuze kudluliselwe idatha ye-optical.
5. Ama-modulators e-fibre optic angasekelwa ezimisweni ezahlukahlukene. Kungaba idivayisi yangempela ye-fiber optic, noma kungaba yingxenye yomzimba equkethe i-fiber pigtails.
6. I-modulator yekristalu yolwelo ifanele ukusetshenziswa emishinini yokubonisa i-optical noma i-pulse shaper. Ingasetshenziswa futhi njenge-modulators yokukhanya kwendawo, okusho ukuthi ukudluliselwa kuyahlukahluka ngesikhala, esingasetshenziswa kumadivayisi okubonisa.
7. Idiski yokushintsha ingashintsha amandla ogongolo ngezikhathi ezithile, olusetshenziswa kwezinye izilinganiso ezithile zokukhanya (njengokusebenzisa ama-amplifier okukhiya).
8. Ama-modulators e-Micromechanical (izinhlelo ze-micromechanical, i-MEMS) njenge-valve yokukhanya esekelwe ku-silicon kanye nama-mirror arrays amabili abaluleke kakhulu ekubonisweni kwe-projection.
9. Ama-modulators e-optical amakhulu, njenge-electro-optical modulators, angasebenzisa indawo enkulu ye-beam futhi angasetshenziswa nasezimweni zamandla aphezulu. Ama-modulators ahlanganiswe ne-fibre, ngokuvamile ama-modulators e-waveguide ane-fiber pigtails, kulula ukuwahlanganisa ezinhlelweni ze-fiber optic.
Ukusetshenziswa kwe-modulator ye-Optical
Ama-modulators e-Optical anezinhlelo zokusebenza eziningi emikhakheni eminingi. Lokhu okulandelayo yizindawo eziyinhloko zokusetshenziswa kwama-modulators e-Optical kanye nezinhlelo zawo ezithile:
1. Ukuxhumana Okubonakalayo: Ezinhlelweni zokuxhumana okubonakalayo, ama-modulators optical asetshenziswa ukuguqula ubukhulu, imvamisa kanye nesigaba sezimpawu zokukhanya ukuze kudluliselwe ulwazi. Ngokuvamile asetshenziswa ezinyathelweni ezibalulekile njengokuguqulwa kwe-photoelectric, ukuguqulwa kwesignali optical kanye nokususwa kwe-. Ama-modulators e-electro-optic abaluleke kakhulu ezinhlelweni zokuxhumana ezisheshayo, ezisetshenziselwa ukuguqula izimpawu ze-elekthronikhi zibe izimpawu zokukhanya futhi zibone ukufakwa kwedatha nokudluliselwa kwedatha. Ngokuguqula ubukhali noma isigaba sesignali optical, imisebenzi yokushintsha ukukhanya, ukulawula izinga lokuguquguquka kanye nokuguqulwa kwesignali ingafezeka
2. Ukuzwa kokukhanya: I-modulator yokukhanya ingabona ukulinganiswa nokuqapha indawo ngokushintsha izici zesignali yokukhanya. Isibonelo, ngokushintsha isigaba noma ubukhulu bokukhanya, ama-gyroscope e-fiber optic, izinzwa zokucindezela kwe-fiber optic, njll. kungabonakala
3. Isitoreji kanye nokucubungula kwe-Optical: Ama-modulators e-Optical asetshenziselwa isitoreji se-optical kanye nezinhlelo zokusebenza zokucubungula kwe-optical. Kumemori ye-optical, ama-modulators e-optical angasetshenziswa ukubhala nokufunda ulwazi ngaphakathi nangaphandle kwemidiya ye-optical. Ekucubungulweni kwe-optical, i-modulator ye-optical ingasetshenziswa ekwakheni, ekuhlungeni, ekuguquleni nasekuhlukaniseni izimpawu ze-optical
4. Ukuthwebula izithombe ngokubona: ama-modulators optical angasetshenziswa ukuguqula isigaba kanye nobukhulu bomsebe wokukhanya, ngaleyo ndlela ashintshe izici zesithombe ekuthwebula izithombe ngokubona. Isibonelo, i-modulator yensimu yokukhanya ingasebenzisa ukuguqulwa kwesigaba okunezinhlangothi ezimbili ukushintsha ubude bokugxila kanye nokujula kokugxila komsebe
5. Ukulawulwa komsindo obonakalayo: I-modulator yokukhanya ingalawula ubukhali kanye nemvamisa yokukhanya, ngaleyo ndlela inciphise noma icindezele umsindo obonakalayo ohlelweni lokukhanya. Ingasetshenziswa kuma-amplifier optical, ama-laser kanye nezinhlelo zokudlulisa i-fiber optic ukuthuthukisa isilinganiso sesiginali kuya komsindo kanye nokusebenza kohlelo
6. Ezinye izinhlelo zokusebenza: ama-modulators e-electro-optical asetshenziswa nasekuhlaziyweni kwe-spectral, izinhlelo ze-radar, ukuxilongwa kwezokwelapha kanye neminye imikhakha. Ku-spectroscopy, i-modulator ye-electro-optical ingasetshenziswa njengengxenye ye-optical spectrum analyzer yokuhlaziywa kwe-spectral kanye nokulinganiswa. Kuhlelo lwe-radar, i-electro-optic modulator isetshenziselwa ukuguqulwa kwesignali kanye nokususwa kwe-demodulation. Ekuxilongweni kwezokwelapha, ama-modulators e-electro-optic asetshenziswa ekuthathweni kwezithombe kanye nokwelashwa kwe-optical .
